FIELD

The technology relates in part to the field of animal husbandry and to animal containment.

BACKGROUND

Animal containment systems are utilized in a variety of applications, such as for animal transportation, breeding and maintenance. Animals contained in the systems often are laboratory animals such as rodents, and such animals often are contained in a vivarium. Containment systems may include animal cages in which the animals are housed and a rack unit onto which cages are mounted. Animals contained in such systems emit several gaseous and particulate contaminates that are health risks to housed animals and human personnel maintaining the systems. Generally, permanent or multiple-use cages are designed for multiple uses, which requires they are washed and sterilized about every week for two years or more in an animal containment facility, for example, especially in a facility practicing Good Laboratory Procedures (GLPs). Multiple-use cages generally are heavy and have relatively thick walls and components often are constructed from resilient materials that can withstand multiple washes and sterilizations. Such cages may be disposed in a rack that holds multiple cages in order to house the animals more efficiently, however, it may be inconvenient to remove the cages from such rack in order to perform cleaning and other maintenance work. Due to these aspects of typical multiple-use animal containment systems, a significant portion of animal containment resources are required for washing and sterilizing multiple-use components. Multiple-use cage designs also can present disadvantages with respect to contamination, such as requiring contaminated air filter handling or exposure of cage components to the environment when a cage impacts a surface (e.g., a cage is dropped by a user or falls from an elevation), for example, which bear especially on handling of animals in higher biosafety level animal facilities. As such, what has been needed are animal containment cages and management systems that eliminate the need for regular washing of cages, provide a safe and healthy environment for contained animals and optionally provide an efficient means for housing and maintaining a large number of animals in a limited space.

DETAILED DESCRIPTION Identifiers

Provided in some embodiments are identifiers, methods of manufacturing identifiers, and use of identifiers to uniquely label or identify one or more items (such as animal cage cards, animal cages or racks or large or small objects), to identify animals, cage components or data for sorting, tracking, identification, verification, authentication, management, inventory, maintenance, or for other purposes. This type of identification technology is useful in helping machines and/or people identify cage components, animals and/or associated data and capture the information. Such identification may include manual interaction by a human operator (e.g., scan an identifier by a handheld device or manually input code or information pertaining to an identifier into a computer reader and/or controller), and often includes automatic data capture where data is automatically recorded by machine and/or device.

Such identifiers may include one or more bar codes, serial numbers, alphanumeric identifiers, text, graphics, watermarks, holographs, electronic microchips/transponders, radio-frequency identification (RFID), reflective identifiers, non-reflective identifiers, magnetic identifiers, symbolic codes, chemical identifiers, magnetic tags/strips/ink character recognition, smart cards, optical character recognition, optical mark recognition, and fluorescence (or other optical techniques), or combinations thereof, for example. An identifier may be a physical code, physical image or physical substance, and can be a representation of data or information or representation of a physical structure. An identifier may be obtained from, determined by or calculated from information obtained from other identifiers. For example a cage lid identifier may be used in reference to the actual bar code placed on a cage lid, or in some embodiments, an identifier can be used in reference to non-tangible information, such as usage history of the cage lid or association of the cage lid to corresponding objects and/or number of animals. In some embodiments having more than one identifier, the identifiers sometimes contain the same information, and sometimes the identifiers have different information. In certain embodiments, identifiers on different cage components include different information and in some embodiments identifiers on different cage components include substantially identical information.

Bar codes may be a series of lines of varying width, printed, as on a container or product, that may be read by a scanner and/or decoded by a computer into usable information. A serial number may be a number, usually one of a series, assigned for identification. A serial number may be a unique number assigned for identification which varies from its successor or predecessor by a fixed discrete integer value. An alphanumeric identifier may be a combination of alphabetic and numeric (also called alphanumeric), and can be used to describe the collection of Latin letters and Arabic digits used by much of western society. A set of 36 (single case) or 62 (case-sensitive) alphanumeric characters may be utilized. An alphanumeric character set often consists of the numbers 0 to 9 and letters A to Z. Text may be the actual wording of anything written or printed or a unit of connected speech or writing, especially composed of more than one sentence, which forms a cohesive whole. Graphics may be a product of the graphic arts, as a drawing, symbol or print, for example. Graphics may generally involve drawing, painting, and printmaking, for example.

Radio-frequency identity (or identification), RFID, is a technology that uses tiny computer chips to track items at a distance. Radio-frequency identification (RFID) is the use of an object (typically a RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader. Radio-frequency identification involves interrogators (or readers), and tags (or labels). RFID tags may contain two parts. One part may be an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second may be an antenna for receiving and transmitting the signal. Generally, there are three types of RFID tags: active RFID tags, which contain a battery and can transmit signals autonomously, passive RFID tags, which have no battery and require an external source to provoke signal transmission, and battery-assisted passive (BAP) RFID tags, which require an external source to be activated and has greater signal range.

Reflective identifiers may be any type of identifier capable of casting back particles (such as, for example, light, heat, sound, electromagnetic radiation, etc). Such identifiers may reflect light, images, or sound waves, for example. Non-reflective identifiers may be any type of identifier not capable of casting back particles.

In some embodiments, one or more identifiers are transparent or opaque to one or more detection means (e.g., electromagnetic radiation). Generally, electromagnetic radiation emitted or absorbed by an object is characteristic of the object's electromagnetic spectrum, which electromagnetic spectrum often can be detected. Electromagnetic radiation often includes features such as electromagnetic frequencies and/or electromagnetic wavelengths and an electromagnetic spectrum sometimes comprises substantially all readily detectable electromagnetic radiation. Transparency and/or opaqueness to one or more electromagnetic features can be predetermined by the use of various detectable materials and detectors. Detectable materials sometimes are part of, included in or layered on materials utilized to generate cage components described herein. In some embodiments, a cage component may be transparent to some wavelengths, but not all electromagnetic wavelengths (e.g., opaque to some wavelengths). In some embodiments, one or more cage components may be transparent to one or more types of electromagnetic radiation chosen from radio waves, micro wavelengths, infrared wavelengths, visible wavelengths, ultraviolet wavelengths, soft x-rays, the like or combinations of the foregoing. In some embodiments, one or more cage components may be opaque to one or more types of electromagnetic radiation chosen from radio waves, micro wavelengths, infrared wavelengths, visible wavelengths, ultraviolet wavelengths, soft x-rays, the like or combinations of the foregoing. The term “opaque” with regard to electromagnetic radiation refers to a cage component and/or identifier allowing transmission of 5% or less of an electromagnetic feature.

Magnetic identifiers, magnetic tags/strips, magnetic ink characters, and/or smart cards may be any type of identifier having properties of a magnet. An example of a system employing magnetic materials is in WO 93/14474, which describes a system that generates an electromagnetic field, to which individual transponder units receive, store, and transmit the identification data, which is then received by a receiver and is incorporated by reference herein in its entirety. Another example of a system employing magnetic materials is in U.S. Pat. No. 4,075,618, which describes an antipilferage magnetic tag detected in an interrogation zone producing an alternating magnetic field by high-order harmonics produced by the presence of the tag and is incorporated by reference herein in its entirety. The tag has an asymmetrically shaped piece of low-coercive force ferromagnetic material, including a centre section and flux concentrator sections at opposite ends of this section. Another example of a system employing magnetic materials is in U.S. Pat. No. 6,144,300, which discloses a magnetic analogue of an optical bar code reader system and is incorporated by reference herein in its entirety. Soft magnetic elements are arranged in a linear array and read by mechanically scanning a coil along the array, the coil generating a magnetic null enabling the elements of the array to respond to the applied field. The spatial arrangement of the elements in the linear array defines a code similar to a bar code.

Symbolic codes or identifiers may be any type of symbol that conveys identify or recognition of any type. A symbol may be something used for or regarded as representing something else; a material object representing something, often something immaterial; emblem, token, or sign. A symbol may be a letter, figure, or other character or mark or a combination of letters or the like used to designate something: the algebraic symbol x or the chemical symbol Au for gold, for example. A symbol also may be a word, phrase, image, or the like having a complex of associated meanings and perceived as having inherent value separable from that which is symbolized, as being part of that which is symbolized, and as performing its normal function of standing for or representing that which is symbolized: usually conceived as deriving its meaning chiefly from the structure in which it appears, and generally distinguished from a sign. A symbol may be commonly known such as a smiley face, or be obscure, non-recognizable, and novel, for example.

Chemical identifiers of any type may be used to signal the presence of a chemical. A chemical identifier may be used in lieu of or in conjunction with any type of sensor. Additionally the chemical identifier may be triggered by an auto-catalytic chemical reaction, for example by the presence of moisture, by the presence of heat and/or pressure, or by the presence of water and/or another chemical such as ammonium, for example. Chemical identifiers also may be called discoloring polymers, where there is a chemical change within polymers used for identification.

An optical identifier of any type may be used. An optical identifier may include an optical substrate or be encoded with optical identification elements, optical character recognition, optical mark recognition, capable of having many optically readable codes. The optical substrate or element may be made of a glass material, such as silica or other glasses, or may be made of plastic or polymer, or any other material capable of having a diffraction grating disposed therein.

Fluorescence identifiers of any type may be used. Fluorescence identifiers may include the emission of radiation or of visible light or luminescence, during exposure to external radiation such as light or x-rays, or other sources of optical emissions, such as an optical reader, for example.

Holographic identifiers also may be used, or any type of two, three, or four dimensional image reproduced from a pattern of interference or produced by a split coherent beam of radiation, as from a laser. A holograph may be an image produced by a hologram, which is a negative produced by exposing a high-resolution photographic plate, without camera or lens, near a subject illuminated by monochromatic, coherent radiation, as from a laser when it is placed in a beam of coherent light a true three-dimensional image of the subject is formed.

For a cage rack system, identifiers can be cage content identifiers, cage component identifiers, cage condition identifiers and cage user identifiers, for example. Identifiers also may be associated with data that pertain to cage content data, cage component data, cage condition data and cage user data identify the same tangible object and/or digital information. For example, a cage lid identifier may refer to the identifier code on the lid, the lid itself, the history of the lid, location of the lid and the like.

Identifiers can be detected by a detector at any suitable speed of cage insertion. In some embodiments an identifier can be detected at a relatively slow insertion speed, and in certain embodiments, an identifier can be detected at a relatively fast insertion speed. In some embodiments changes in the rate of cage insertion velocity (e.g., increasing speed of cage insertion, decreasing speed of cage insertion, increasing then decreasing speed of cage insertion, decreasing then increasing speed of cage insertion, the like or combinations of the forgoing) do not effect a detectors ability to accurately detect an identifier.

Location of Identifiers

One or more identifiers may be located in any location, such as on an animal cage card, on the back of a cage component, on the side or sides of a cage component, on the top of a cage component, on a cage component flange, on a rack module or rack module component, in a rack side member or support member, on one or more other cage or rack items/components, on non-cage items (e.g. a personnel identification badge, medication, drug dosing card, investigator card, veterinarian records, etc), or combinations thereof, for example. Identifiers on one or more cage components (e.g. a lid, a base, an air supply component, an air exhaust component, a water supply component, a sensor component, a filter component, a baffle component, a feeder and the like), may be located near another identifier, adjacent to another identifier, overlapping another identifier, on top of another identifier, or in any location where data from the identifier may be captured or accessed. The identifiers also may be in-line with one another or in-line with another component. The term “in-line” as used herein pertains to a linked sequence of placement, such as, sequentially within a line or one identifier behind another identifier thereby forming a straight line.

The location of identifiers may be visible or invisible to a cage user. The location of identifiers may be determined by an identifier reader, such as by an optical reader, for example. Inventory of identifiers within a specified location may be determined by an identifier reader, for example by using a RFID reader.

Non-limiting examples of identifier locations are shown in FIGS. 1-3, 7, 22, 54, and 65-68. FIGS. 1 and 65 show a top perspective view of cage lid 132 having a filter element 135, two nozzles 66 and 68, press-in post couplers 138 and lid identifier 400. FIG. 65 shows a lid embodiment having two identifiers 400. The lid identifier 400 may be on a flange of the lid 132. Identifier 400 may be on the bottom surface of the flange or on the top surface of the flange of the cover and/or base. FIGS. 2 and 66 show a top perspective view of the cage bottom 130 having bottom or base identifier 402. FIG. 66 shows a cage bottom embodiment having two identifiers. The bottom identifier 402 may be on the top or bottom of a flange of the base 130. The identifier 402 may be on the bottom surface of the flange or on the top surface of the flange. FIGS. 3 and 67 show a top perspective view of cage lid 132 on top of cage bottom 130 where the bottom identifier 402 can be seen through the transparent cage lid 132. As shown in FIGS. 3 and 67, the identifiers 400 and 402 are in-line with the flanges and in-line with each other. FIG. 67 shows an embodiment of a cage lid on top of a cage bottom where both the cage lid and cage bottom have two identifiers. Placement of in-line identifiers may aid in the quick scanning or identification of the identifiers by a reader, for example. One or more other identifiers may be placed in-line with the lid identifier 400 and bottom identifier 402 such that the third or more identifiers will be scanned or read by a reader. FIG. 7 shows a front perspective view of a cage 20 with a cage card 410 and seven separate cage card identifiers 412. FIGS. 22 A-B and FIGS. 68A-B show top and isometric views of cage 20 with cage identifiers 400 on either side of cage 20. FIGS. 54A and 54 b show isometric views of cage 20 with cage identifiers 400 on either side of cage 20. In one embodiment, a cage card identifier or cage content identifier 412 may contain two identifiers, one being a symbol (smile face) and the second being bar code/serial code which may be detected by a reader. Each different cage card identifier 412 for separate cages may have different symbolic and bar code/serial code identifiers from each other such that all of the cage card identifiers are unique. For example, one cage card identifier may have a smiley face symbol, another cage card identifier may have a star symbol, another cage card identifier may have a cloud symbol and the like. Cage card identifiers may have one or more identical identifiers, such that one or both of the two identifiers on the cage card identifier is the same as another cage card identifier. One of the perforated/adhesive cage card identifiers 412 may be placed in-line with bottom identifier 402 and lid identifier 400 such that all three identifiers will be read by a reader. Other perforated/adhesive cage card identifiers 412 may be placed on objects that have an association or correspond to the identifier or occupants of the animal cage which the cage card identifier 412 is attached or belongs to.

In some embodiments, one or more identifiers can be located on a cage lid, cage base or both cage lid and cage base. In certain embodiments, two or more identifiers can be located on a cage lid, cage base or both cage lid and cage base. In some embodiments, a first and second identifier are on opposite sides along the length of a cage. The identifiers can be the same or different. Identifiers that are the same encode redundant information. A reader can be located above a cage, as shown in FIGS. 23A-C and FIGS. 69A-C, identifiers on the cage lid or cage base or both are placed such that the readers can detect them as the cage is contacted and moved along the cage mount guide rails of the cage mount assemblies. In a certain embodiment, Identifiers may be on the opposite long sides of a cage lid that is attached to a cage base as shown in FIGS. 22A-D, 54, 58, and 65-68A-B. In some embodiments, the identifier is a barcode. Identifiers on opposite sides of a cage lid are simultaneously read by devices, such as cage readers, located on the front of adjacent cage mount assemblies as a cage is slid into the cage mount assemblies and the identifier passes the device.

In some embodiments, one or more identifiers are configured so they do not overlap with one another. In certain embodiments, one or more identifiers are configured so two or more identifiers overlap. In some embodiments having overlapping identifiers, the identifiers can be offset from each other thereby generating regions of non-overlapping identifiers and regions of overlapping identifiers. In some embodiments, overlapping identifiers are detected by the same detector, and in certain embodiments, overlapping identifiers are detected by different detectors. In certain embodiments, each identifier in an overlapping identifier configuration is detected by a different detector. In some embodiments, each cage component has 2 or more, 3 or more, 4 or more, or more than 5 independently detectable identifiers, and in certain embodiments, a subset or all of the independently detectable identifiers can be detected in various combinations. In some embodiments having two or more identifiers (e.g., overlapping or non-overlapping), portions or all of the identifiers may be redundant.

Manufacturing of Identifiers

Techniques for applying one or more identifiers may include, but are not limited to, printing (e.g. impact, ink jet, laser, thermal transfer printing, flexographic, rotogravure, offset or rotary screen and the like), imprinting, embossing, molding, laminating, heating, spraying, rolling, silk-screening, painting, fastening, adhering with adhesives, or any other technique suitable for applying the identifier as described herein. Ink or markings used may be colored or colorless in the visible spectrum. Identifiers may be made with conductive inks that can store and transmit data, and/or made to be fluorescent under certain electromagnetic radiation. Any variety of electronic inks with conductive, insulating, or semiconductor qualities may be used and can be printed in one or successive layers on any material such as plastic substrates or polymer films. The electronic inks also may be opaque, or transparent and thus undetectable to the human eye. Identifiers may be made of organic and/or biodegradable material. Identifiers may be chipless or made on polymer-based tags. Identifiers may be manufactured to allow for a large number of distinct codes, to be made flexible or bendable, and/or to withstand harsh environments.

An identifier may vary in size, shape, color, texture, and the like. Identifiers may be relatively small microelements, microparticles or encoded particles for smaller applications (about 1-1000 microns), or relatively larger macroelements for larger applications (e.g., 10-1000 cm or larger). An identifier also may be embedded within, or part of, a larger substrate, element or object. An identifier also may be in the form of a thread, fiber or filaments that can be weaved into a material. Also, an identifier may be embedded in a film or coating, which may be an adhesive film, coating or tape, having one or a plurality of particles or filaments therein. For example a roll of encoded adhesive tape may be attached to an item for labeling. Identifiers that are embedded inside (e.g., on or near the surface) of a substrate and/or surface, may be permanent, non-removable identifiers that can operate in relatively harsh environments (e.g., subjected to harsh chemicals, temperature, pressure, electromagnetic, etc.).

Identifiers may or may not be affected by spot imperfections, scratches, cracks or breaks in the substrate and/or surface carrying the identifiers. Identifiers may be produced such that they are spatially invariant, where splitting or slicing an identifier axially produces more elements with the same code such that the code is not lost, but instead replicated in each piece.

Identifiers also may be coated by paint, a protective coating or the like. Identifiers may be layered onto each other or overlapping each other such that the combination of two or more identifiers overlapping each other represents a unique code. Identifiers may be identified, recognized, and/or transmit data through other objects (e.g., an identifier may be detected and transmit information through a lid component (e.g., through a flange of a lid)). Sometimes identifiers transmit different information based on the method of detection used. In some embodiments one or more types of information may be layered in one or more identifiers, and in certain embodiments, the different types of information may be detected by one or more detectors. In some embodiments, the layered information may be present in non-overlapping identifier regions. In certain embodiments, the layered information may be present in overlapping identifier regions. In some embodiments, the layered information may be present in non-overlapping identifier regions and in overlapping identifier regions. For example, identifiers that are transparent to some electromagnetic wavelengths and opaque to other electromagnetic wavelengths sometimes allow detection of different information based on the type of detector used for detection. The term “different information” as used with regards to layered information present in identifiers refers to one or more types of information that can be encoded in an identifier, which information sometimes can be detected under certain detection conditions, but not other detection conditions (e.g., detected with certain electromagnetic wavelengths, but not other electromagnetic wavelengths).

Identifiers and/or detection of identifiers also may be modified by one or more additives added to materials from which cage components are manufactured. In some embodiments, one or more additives added to polymers used to manufacture cage components described herein can alter transparency or opaqueness of a cage component to various types of electromagnetic radiation used to detect one or more identifiers.

Detectors and Readers

An identifier may be read visually by a user or may be read by a machine (e.g., automated detection). Machines that detect, scan and/or identify identifiers are referred to herein as “readers” or “detectors.” Some identifiers are detected, scanned and/or identified without use of a reader, and some identifiers are detected, scanned and/or identified with the use of a reader. A reader may be a mechanical machine, and in some embodiments, a reader includes one or more magnetic optical components. A reader may be mounted to a cage system component (e.g., a rack in an automated reading configuration) and/or may be a handheld device in some embodiments. The output, input or a signal to or from a reader can be directed and received by a controller, computer, main server, local server, database, another reader or by a device that has a visual display such as an indicator, in certain embodiments. In some embodiments, a reader is write enabled. That is, in some embodiments a reader can alter the information content encoded on a cage component by altering (e.g., adding to, removing from or changing) a cage component identifier.

Any convenient configuration of one or more indicators can be utilized. An indicator may be relatively simple, such as a device having a red and green light, which can indicate two states, such as, yes or no, open or closed, and the like, for example. An indicator may respond to identification of an identifier or location of an identifier by a signal other than a visual signal, such as an auditory, tactile, or olfactory signal, for example. An indicator can be a graphic display of one or more rack systems, and show cage positions associated with one or more criteria (e.g., user-defined criteria or pre-programmed criteria) in certain embodiments. A reader may be integrated with an indicator, such that a reader can respond to identification of an identifier or location of identifier by producing a visual, auditory, tactile, or olfactory signal. Thus a reader may be synonymous to an indicator.

A reader may comprise a detector, which detects an identifier and delivers electrical signals to a controller, the latter of which processes electrical signals transmitted by the detector i to produce a visual display or data of, for example, information about/recorded by the identifier and/or location of the identifier. A reader may be in wireless communication or directly connected to a controller and/or computer processor. A reader may be a mobile device with a scanner operably coupled to the mobile device. The scanner may include a light source, a lens, a photo conductor which translates optical impulses into electrical impulses, an output port, and the like, in some embodiments. Readers also may include decoder circuitry which analyze an identifier's image in certain embodiments.

Any variety of readers may be utilized to detect identifiers, such as a device that can detect an identifier described herein. Non-limiting examples of readers include pen type readers, laser scanners, CCD readers, camera based readers and the like. In some embodiments, an identifier is moved past a relatively stationary reader and the reader detects the identifier before, during or after the identifier is in detectable proximity with the reader. In certain embodiments, the reader is moved past a relatively stationary identifier and the reader detects the identifier before, during or after the reader is in detectable proximity with the identifier. An identifier and reader may be moved past the other (e.g., moved over the other, moved near the other) in a suitable or convenient manner, such as by a user or by an automated translation device (e.g., a robot may move a cage component or components past a reader or move a movable reader past a cage component). A reader may detect a signal emitted from an identifier in some embodiments, and sometimes a reader can detect a signal first generated by the reader and then transmitted back to the reader from the identifier (e.g., reflected by the identifier). A signal transmitted to a reader from an identifier may be processed or decoded by the reader in some embodiments, and the processed signal may be forwarded to another part of a system (e.g., processor and/or controller). In some embodiments, a signal is two or more signals (e.g., 2 or more signals, 3 or more signals, 4 or more signals, or more than 5 signals). In certain embodiments, each signal is the same signal, and in some embodiments, each signal is a different signal. In embodiments having two or more different signals, each signal may be detected by the same detector or one or more signals may be detected by a different detector. A signal transmitted to a reader from an identifier may be forwarded directly, without processing or decoding, to another part of a system (e.g., processor and/or controller) in certain embodiments. In the latter embodiments, another part of a system may process and/or decode an identifier signal detected by the reader. Certain specific types of readers that can be utilized are described hereafter.

Pen type readers can include a light source and a photodiode placed next to each other in the tip of a pen, wand or projected device, in some embodiments. To read an identifier, the tip of the pen or device often moves across the bars of an identifier in a steady motion. The photodiode measures the intensity of the light reflected back from the light source and generates a waveform that is used to measure the widths of the bars and spaces in the identifier. Dark bars in the identifier absorb light and white spaces reflect light so that the voltage waveform generated by the photo diode is a representation of the bar and space pattern in the identifier. This waveform is decoded by the scanner in a manner similar to the way Morse code dots and dashes are decoded.

Laser scanners are similar to pen type readers except that they may use a laser beam as the light source and may employ a reciprocating mirror or a rotating prism to scan the laser beam back and forth across the identifier. Similar to a pen type reader, a photodiode is used to measure the intensity of the light reflected back from the identifier. In pen readers and laser scanners, the light emitted by the reader often is tuned to a specific frequency and the photodiode is designed to detect modulated light of the same frequency.

CCD readers (also referred to as LED scanner) use an array of (e.g., hundreds of) tiny light sensors lined up in a row in the head of the reader. Each sensor can function as a single photodiode that measures the intensity of light immediately in front of it. Each individual light sensor in the CCD reader often is small and because there are a plurality of sensors lined up in a row, a voltage pattern identical to the pattern in a bar code is generated in the reader by sequentially measuring the voltages across each sensor in the row. A difference between a CCD reader and a pen or laser scanner sometimes is the CCD reader is measuring emitted ambient light from the identifier whereas a pen or a laser scanner is measuring reflected light of a specific frequency originating from the scanner itself

A camera-based reader or 2D imaging scanner also may be used. Such a device often makes use of a small video camera that can capture an image of an identifier. The reader then may make use of a digital image processing technique to decode the identifier. Video cameras use the same CCD technology as in a CCD identifier reader except that instead of having a single row of sensors, a video camera has hundreds of rows of sensors arranged in a two dimensional array so that they can generate an image.

A reader may be located in any suitable or convenient location on a device, such as on a rack, on a shelf, on a cage mount assembly, on an animal cage, on a controller, on a computer, or on a hand-held device, for example. Different types of readers may be used in combination. Or only one specific type of reader may be used. In some embodiments, readers may be configured with a water tight seal, to allow washing of a rack without the need for reader removal. In some embodiments, a translucent faceplate or cover is used to seal the LED's sometimes used as the indicators in a reader.

Use and Function of Identifiers

It is often desirable to uniquely label or identify items, such as cage components, cage contents (e.g., animals), cage conditions, and cage user information for sorting, tracking, identification, verification, authentication, inventory, billing, management, anti-theft/anti-counterfeit, security/anti-terrorism, forensics, and/or for other purposes. One issue regarding maintenance of a rack system and the animals contained within the cages supported by the rack system concerns efficient and accurate gathering, processing and displaying information regarding the interior conditions of each cage to lab personnel. In many circumstances regarding the care and maintenance of systems or studies involving multiple containment cages that house laboratory animals, the cages are cleaned, changed or otherwise maintained on a regular schedule that may be dictated by good laboratory practices and may also include the input of a veterinary professional. Because of the complicated nature of the interaction of an animal with its surroundings, maintenance schedules may often be calculated or determined based on a worst case scenario for a group of cages. More specifically, the maintenance schedule for all cages may be determined by the cage having the highest bio-burden as it is too time consuming to monitor each cage individually. For such an arrangement, cages not immediately requiring maintenance will receive it anyway, resulting in a non-efficient use of laboratory resources and unnecessary maintenance of some cages having a lower bio-burden or the like. In addition, even if cage monitoring data is available remotely to laboratory personnel, if laboratory personnel are tasked with monitoring a large number of cages, it may still be burdensome to process all the cage data.

Identifiers may serve any suitable or convenient purpose. For example, identifiers may be clocking identifiers, cage position identifiers or location identifiers, content identifiers, user identifiers, cage component identifiers, cage condition identifiers or combinations thereof. A clocking identifier may measure and record time and/or speed by which the identifier was read. A clocking identifier may also function as a meter, a speedometer or taximeter, for measuring and recording speed, distance covered, or other quantitative functioning of how the identifier was read or data acquired.

Information from one identifier may be associated with information from another identifier in some embodiments. Information from an identifier can be associated with information not generated from an identifier, such as, for example, information inputted or read by a user or machine (e.g., cage card information, cage content information, cage user information, information entered by a user into the rack controller).

In certain embodiments, a cage position identifier or location identifier may act in collaboration with one or more other indicators, readers, identifiers, systems, sensors or components to disclose its location. A cage position identifier or location identifier may store location information regarding its position in relation to other identifiers and or other cage components or other relative location (e.g., a GPS location), in some embodiments. In certain embodiments, a cage position identifier or location identifier may transmit a wireless GPS signal to a reader, controller or computer having a digital screen to display the location when the identifier is moved, soiled, or activated by a variety of actions.

In some embodiments, a cage content identifier may contain information regarding the occupants of the animal cage such as the number and type of animals in a cage, the owner of a cage, the age of an animal, the sex of an animal, the pedigree of an animal, the experimental procedure planned for an animal, the observations/notes by a cage user, or the like. A cage user identifier may contain information regarding users of the rack system or of one or more cages such as the personnel accessing a cage, the time of cage access, the date of cage access, the purpose of cage access or the like.

In certain embodiments, a cage component identifier may label or identify an object the identifier is located on, for example a cage lid component, a cage base component, an air supply component, an air exhaust component, a water supply component, a sensor component, a filter component, a baffle component, a bedding component or a feeder or the like.

In some embodiments, a cage condition identifier may contain information regarding any conditional changes made to the inside or outside of the cage itself or any materials used in maintenance of the cages, such as a food change, a water change, a medicine administered to the occupants of the cage, a bedding material change, a filter change, a syringe administered to one or more animals, a glove used by personnel cleaning the cages, cleaning supplies used to clean the cages or the like. A cage condition identifier may also contain a time/date stamp of when the non-cage material was used for the cage or when the cage was maintained. In some embodiments, a cage condition identifier comprises a bedding component, and in certain embodiments a bedding component identifier comprises a sensor chosen from a chemical sensor, RFID sensor, thermal sensor, moisture sensor, the like and combinations of the foregoing.

FIG. 7 shows a front perspective view of a cage 20 with a cage card 410 and several cage card identifier or cage content identifiers 412 in a row. FIG. 7 shows the cage card 410 mounted onto the front of the cage bottom 130 with information displayed, such date, study # and investigator. There are seven cage card identifiers 412 horizontally lined up next to each other that have perforated sides such that a user may tear or detach each identifier separately from the cage card. The cage card identifiers 412 also may have an adhesive backing such that they will stick to other surfaces. Each identifier has a symbol and a bar code or serial code. The symbol on the identifier 412 is a smiley face. In maintaining a disposable animal cage, the cage bottom 130 and/or cage lid 132 may be replaced. Upon replacing the cage bottom 130, the cage card 410 can be taken off the old cage bottom and attached to the new cage bottom. In some embodiments, cage components, such as a cage lid or cage bottom, that are associated with a specific cage or a cage card 410, can be placed with the same identifier such as 412 for tracking. If a reader is located above a cage, as shown in FIGS. 4A-D, identifiers of cage components and cage content identifiers 412 may all be placed in-line such that the reader can detect them as the cage is inserted into the shelf rack assembly. Personnel switching an old cage bottom for a new cage bottom may perforate one cage card identifier 412 from the cage card 410 and place it on the flange of either the cage lid 132 or cage bottom 130, in-line with the identifiers 400 and 402 such that the reader 400 can now identify the three identifiers together and thus associated them together. After changing the cage bottom 130, the new cage bottom has a new cage bottom identifier 402 and is associated with the correct/corresponding cage content identifier 412 and cage lid identifier400. The old cage bottom and the new cage bottom may have the same identifier code. The old cage bottom and the new cage bottom may have different identifier codes. The location of the identifiers at the same coordinates may associate them together. The detection of the identifiers at the same time/date may associate them together. Detecting the identifiers by the same reader may associate them together and the like.

By detecting and processing information from identifiers, systems and methods described herein can allow lab personnel to reliably and conveniently monitor the interior conditions of each individual cage supported by a rack system with cage status information being conveniently and efficiently displayed. Also, systems and methods provided herein can allow for tracking cage component inventory and placing orders for cage components from a manufacturer or distributor. Systems and methods provided herein can allow for tracking of cage conditions and identification of cages that share certain conditions (e.g., amount of food and/or water placed into a cage and when each amount was placed in the cage; type and amount of drug administered to specific animals in a cage and time and date of such administration). Systems and methods herein also can allow for tracking of certain activities associated with vivarium personnel, thereby providing for efficiency and security determinations (e.g., which personnel handled a particular cage, when certain personnel handled a cage, how often certain personnel handled a cage). Some of these functions are described further in the section herein entitled “Processors, Controllers and Servers.”

In certain embodiments shown in FIG. 9, a rack system 210 includes a controller 230 that may be coupled to a blower assembly 224 and 226 and one or more sensors (not shown). The sensors include any of a variety of configurations or types that may be used to monitor conditions within each individual cage 20 supported by rack system 210. The data obtained by the controller 230 from the sensors, identifiers, or other sources may be processed by a computing system disposed within the controller, main server, local server or any other suitable location in the system that may include a processor and data storage device and then displayed on a graphic user interface in a convenient visual display format.

In certain embodiments shown in FIG. 26, cage rack system 500 includes controller 580 that may be coupled to blower assembly 600, 700 and one or more sensors (not shown). The controller can be mounted on the top of a side member 504, 506 or on the side of a side member. In one embodiment, the controller can be mounted on a controller side mount 582. The sensors include any of a variety of configurations or types that may be used to monitor conditions within each individual cage 20 supported by cage rack 500. The data obtained by controller 580 from the sensors, identifiers, or other sources may be processed by a computing system disposed within the controller, main server, local server or any other suitable location in the system that may include a processor and data storage device and then displayed on a graphic user interface in a convenient visual display format. In some embodiments, a controller can communicate with blower assembly 600, 700 and one or more sense wirelessly.

Cages

Some animal containment cage embodiments may include a containment cage base member, a cover or lid member, and an optional insertion member or device. An animal cage base sometimes is provided separately from a lid, the lid often may be attached to the cage base and the lid may be readily detachable from the base. An animal, such as a rodent, and/or optional insertion member may be placed in a cage base before a lid is attached. A variety of animals may be contained within cage embodiments described herein. Rodents often are contained within such units, including but not limited to mice, rats, hamsters, gerbils, guinea pigs, chinchillas and rabbits. The animal can be transgenic, inbred, immunodeficient, lack one or more functional genes (e.g., knock-out animal), and/or can include one or more xenografts. Examples of immunodeficient mice include nude mice and severe combined immune deficiency (SCID) mice. Cells from cultured cell lines, cultured primary cells or directly from another animal or tissue (e.g., biopsy) may be utilized for xenografts (e.g., cancer cells from a human). The animals contained in cages and systems described herein can be utilized in a variety of manners, including but not limited to studying cancer and other diseases, assessing parameters of potential drugs (e.g., toxicity, efficacy, maximum tolerated doses, effective doses and other pharmacokinetic parameters), producing and isolating antibodies and producing and isolating cells useful for preparing hybridomas, for example.

Cage base embodiments may be of any geometry suitable for housing animals, such as cylindrical, substantially cylindrical, conical, rectangular, square, cubic, rhomboid and the like, for example. Cage base embodiments may include a bottom member that supports a plurality of sides or sidewall members (e.g., four sidewall members). One sidewall member may be referred to as a “front sidewall member” and the opposite sidewall member may be referred to as a “rear sidewall member.” Opposing sidewall members sometimes are parallel, substantially parallel, not parallel, rhomboid, substantially rhomboid or a combination thereof. In some embodiments, opposing sidewalls are not parallel, and are not vertical or perpendicular with respect to the bottom. In such embodiments, a sidewall, and sometimes all sidewalls, are at a non-90 degree angle with respect to the bottom, such as an angle between about 91 degrees and about 105 degrees, an angle of about 92 degrees to about 98 degrees or an angle of about 95 degrees, for example. Such angled sidewall configurations (with respect to the bottom) can promote cage base nesting (described in greater detail hereafter).

In certain embodiments, a guide member and/or support member is a flange, projection, rib or groove located on the exterior surface of a bottom member of a base and/or one or both cage sidewall members (e.g., sidewall member adjacent to the front sidewall and rear sidewall), and often may be parallel with the top edges of the sidewall members. Such guide members and support members sometimes extend from the front edge of a sidewall member, sometimes extend to the rear edge of a sidewall member, sometimes extend from a point in a sidewall member a distance from the front edge, and sometimes extend to a point in a sidewall member a distance from the rear edge. Such members sometimes are oriented in the middle half of the vertical length of a sidewall member, and sometimes are oriented in the middle of the vertical length. In some embodiments, guides are low profile, and sometimes are grooves or depressions, that do not substantially interfere with nesting of cage bases.

Some cage base embodiments may be manufactured from any material suitable for housing an animal, such as a small rodent, for a time period of about one week or greater. The material may be rigid, and often is a semi-rigid or flexible material. The cage base sometimes is constructed entirely, or in part, from a translucent or transparent material. The material sometimes includes additives that alter the transparency or opaqueness of the cage base to various types of electromagnetic radiation. Examples of materials that may be utilized for manufacture of any of the a cage base or lid embodiments discussed herein include, but are not limited to, polypropylene (PE), high-density polyethylene, low-density polyethylene, polyethylene teraphthalate (PET), polyvinyl chloride (PVC), polyethylenefluoroethylene (PEFE), polystyrene (PS), high-density polystryrene, acrylnitrile butadiene styrene copolymers and the like. In certain embodiments, a cage is constructed from PET or PS (e.g., high density PS). For any of the embodiments discussed herein, it may be desirable to use a photodegradable or biodegradable material in order to reduce the impact of the use of disposable type cage assemblies on landfills and other waste management depots. One such material may include a biodegradable PET, such as a biodegradable PET by BioLand from Advanced Extrusions in Minnesota. Such a biodegradable PET material may include the polyethylene terephthalate and an organic additive which creates an extension of the polymer chain that is highly attractive to microbes. Some such additives may be used that do not degrade the strength, stiffness, impact resistance, abrasion resistance, gas barrier properties or migration propensity of the material. Some biodegradable PET materials may have a specific gravity of about 1.3 grams per cm2 and a tensile strength of about 7,000 psi to about 8,500 psi.

A cover or lid may be provided separately from a cage base, often reversibly mates with a cage base, sometimes in sealing attachment, and may be of any suitable geometry allowing for attachment to base embodiments, including sliding attachment. Some lid embodiments may include one or more members that directly mate with and seal with one or more members of a base; sometimes has no side wall members; and sometimes is planar or substantially planar. Some lid embodiments may be constructed from any material that allows for animal containment for about one week or greater. Materials for constructing a lid sometimes are selected to allow for sealing or partial sealing attachment to a cage base. Examples of materials from which lid embodiments may be constructed include those described above for cage base embodiments. Additives that alter the transparency or opaqueness of cage base embodiments also can be used in lid embodiments. Non-limiting examples of additives that alter the transparency or opaqueness of a cage component include chemical additives, metallic additives, particulate additives, films, inks, dyes, and other additives that alter the absorption or transmission of electromagnetic radiation passing through a cage component. Sometimes the lid and base are constructed from the same material and sometimes are of a similar or the same thickness as a thickness of a corresponding base.

Some lid embodiments may be flexible or semi-rigid and include a substantially planar region and a flange region. The substantially planar region may include one or more components described herein. A flange region of lid embodiments sometimes is embossed, may be raised and may includes a region that extends downwards as a lip (referred to herein as a “lip”). A flange and optional lip region may extend continuously around the perimeter of lid embodiments. The profile of the flange and optional lip often correspond to a flange and optional lip on a cage base, and may allow the lid to seal or partially seal with some base embodiments. The flange and optional lip may include any suitable shape to fit with corresponding base embodiments, and sometimes are S-shaped, V-shaped, J-shaped and U-shaped, upwards or inverted, for example.

In some embodiments the lid includes one or more connectors adapted to receive an air supply or air exhaust component or water supply component (e.g., a nozzle or nozzle receptacle). A connector can be of any geometry to receive a corresponding connector from an air supply, air exhaust or water supply component. The cage lid connector often mates with the air supply, air exhaust or water supply connector by a sealing attachment, and often by a reversible connection, and the connectors are of any suitable type. For example, the connection may be defined by cylindrical, square, rectangular or conical side geometry, and flat, rounded, tip or point geometry for the top or bottom, for example. The connecting member in the lid may be a protrusion or a void (e.g., concave or convex, respectively) that receives a corresponding mating void or protrusion, respectively.

One or more cages may be stored on or in a rack module, and any convenient configuration for storing a cage can be utilized. A cage sometimes is placed on a surface of a rack module and stored for a period of time. A cage often resides on a shelf or rail connected to a rack. A rack module sometimes includes one or more mount members useful for storing one or more cages in or on the rack module. A corresponding mount member sometimes is located on one or more outer surfaces of a cage and is adapted to connect with a mount member located on a rack module. In certain embodiments, a mount member is a groove or flange on one or more surfaces of a rack module and is adapted to receive, sometimes slideably receive, a corresponding flange or groove on or in a cage. There may be sufficient distance between the top of a mounted cage and the lower surface of a rack module located above the cage to permit airflow out of the cage in such embodiments.

As discussed above, for any of the cage system embodiments discussed herein or components thereof, including the base 130 and lid 132, it may be desirable to use a photodegradable or biodegradable material in order to reduce the impact of the use of disposable type cage assemblies on landfills and other waste management depots. One such material may include a biodegradable PET, such as a biodegradable PET manufactured by BioLand company. Such a biodegradable PET material may include the polyethylene terephthalate and an organic additive which creates an extension of the polymer chain that is highly attractive to microbes. Some such additives may be used that do not degrade the strength, stiffness, impact resistance, abrasion resistance, gas barrier properties or migration propensity of the material. Some biodegradable PET materials may have a specific gravity of about 1.3 grams per cm2 and a tensile strength of about 7,000 psi to about 8,500 psi.

A rack unit generally includes one or more cage mount support members attached to two side members where the side members often are parallel or substantially parallel and cage mount support members often are parallel or substantially parallel. Rack unit embodiments may be constructed from any suitable material. Non-limiting examples of materials used to construct a rack unit include metal alloys (e.g., sheet metal), polymers, the like and combinations of the foregoing. A rack unit often comprises airflow components, often located internally, such as plenums, apertures and connectors which are described hereafter. A rack unit sometimes includes additional components, non-limiting examples of which include one or more blower units, a power supply, a controller unit, communication medium, cage readers and other desired devices.

In some embodiments, a rack unit is mounted onto a trolley assembly. Sometimes a trolley assembly is configured as a base for one or more rack units and for transportation of a rack unit or plurality of rack units. The trolley assembly includes a trolley frame tube and trolley plate mounts onto which the rack unit is mounted in certain embodiments. In some embodiments, a trolley assembly has two trolley plate mounts attached at each end for mounting of a side member. In some embodiments, the trolley assembly includes coasters or wheels. In certain embodiments a trolley assembly has more than one set of trolley plate mounts attached to each end to accommodate more than one rack unit. In certain embodiments, two rack units are attached to a trolley mount, sometimes back to back and sometimes side to side.

In some embodiments, a rack unit is configured for use with smaller rodents (e.g., mice), and in certain embodiments a rack unit is configured for use with larger rodents (e.g., rats). Rack units can be configured with any number of cage stations suitable for use with the desired type and/or size of rodent. In some embodiments a single rack unit is configured with up to 96 cage stations when configured for use with smaller rodents, and in certain embodiments, the cage stations are configured in an array of 8 columns×12 rows. In some embodiments two rack units configured for use with smaller rodents can be connected to generate a double rack unit with up to 192 cages. In some embodiments a single rack unit is configured with up to 40 cage stations when configured for use with larger rodents, and in certain embodiments, the cage stations are configured in an array of 5 columns×8 rows. In some embodiments two rack units configured for use with larger rodents can be connected to generate a double rack unit with up to 80 cages.

Cage Mount Support Members

Cage mount support members generally are disposed between and connected to the side members. In some embodiments, a cage mount support member includes plenums for the movement of air through the rack system and includes docking positions for engagement of cages. In some embodiments the cage mount support members are disposed between two side members, are substantially perpendicular to the side members and cage mount support members and are substantially parallel to each other. A rack unit generally has one or more cage support members, sometimes 1 to 20 support members (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 or 19 support members). In some embodiments a rack unit has twelve cage support members. In certain embodiments, a rack unit has 8 cage support members.

Generally, the length of the cage mount support member is dependent on a desired or pre-determined width of the rack unit or the number of cages that can be attached to a cage mount support member. Generally, the number of cages that can be attached to a cage mount support member is 1 to 20 cages (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 13, 14, 15, 16, 17, 18 or 19 cages). In some embodiments, the number of cages that can be attached to a cage mount support member is eight. In certain embodiments, the number of cages that can be attached to a cage mount support member is five.

A cage mount support member generally includes an upper surface and a lower surface and one or more channels or plenums. A cage mount support member can have any suitable profile, and non-limiting examples include rectangular, cylindrical and elliptical. The upper and lower surface of a cage mount support member generally is planar or curved and sometimes the surfaces are joined together (e.g., directly or indirectly) and/or are contiguous. In some embodiments, the cage mount support member is elliptical or semi-elliptical with the upper surface convex relative to the lower surface and with rounded junctions between the upper and lower surfaces. In some embodiments, a cage mount support member and plenums within are of a unitary construction.

The channels or plenums of a cage mount support member generally are independent, with substantially no air communication between the plenums. The plenums extend substantially the length of the cage support member in certain embodiments. In some embodiments, one or more walls (e.g., continuous or sections attached to each other) of the cage mount support member contain a first support member plenum and a second support member plenum that extend substantially the length of the cage mount support member. The plenums generally are tubular and can have any suitable profile, non-limiting examples of which include rectangular, cylindrical and elliptical. Plenums within a cage mount support member, or among different cage mount support members in a rack, can have the same or different profiles. In some embodiments, the profiles of the two plenums in a cage mount support member are generally elliptical. A plenum can include any suitable number of walls and sometimes shares one or more walls of a cage mount support member, and/or one or more walls with another plenum in the same cage mount support member (e.g., share a dividing wall). In some embodiments, a cage mount support member includes two plenums that are separated from one another and do not share a dividing wall.

A cage mount support member in some embodiments can be directly abutted against the side member or connected via a connector (e.g., a sleeve). In some embodiments, there is a gasket between a cage mount support member and a side member to provide a substantially air tight seal at the junction of the cage mount support member and the side member. The gasket can be manufactured from any suitable material, and in certain embodiments, the gasket can be manufactured from silicone rubber (other non-limiting examples of gasket materials are described herein). A cage mount support member may be fastened or mounted to a side member by any suitable connection or connector, and non-limiting examples include a threaded connector (e.g., screw), pin, weld or welds, adhesive or by friction. In certain embodiments, one or more screws or bolts (e.g., 2, 3, 4 or 5 or more screws or bolts) are inserted through a side member into bosses or depressions in a cage mount support member.

A cage support member generally has one or more sets of cage connection apertures in the wall or walls of a lower surface. Each cage connection aperture generally is in connection with a single plenum. In some embodiments, a cage support member includes a first set of cage connection apertures in connection with a first support member plenum and a second set of cage connection apertures in connection with a second support member plenum. The cage connection apertures can be in any suitable configuration. In some embodiments the cage connection apertures are regularly spaced across a longer length (i.e., transverse axis) of a cage mount support member. Sometimes, the first set of cage support apertures are disposed along an axis that is parallel to a second axis on which the second set of cage support apertures are aligned. In some embodiments, a first set of cage support apertures are disposed on an axis that is parallel to a second axis on which the second set of cage connection apertures are aligned and each of the apertures in the first set of apertures is offset from apertures in the second set of apertures. Generally, the configuration of cage connection apertures matches the configuration of the protrusions in the cage covers, which are also offset, such that when a cage is inserted into a rack the cage protrusion connection assemblies in contact with the first and second set of cage connection apertures are positioned over and can contact the protrusions in the cage cover. A cage mount support member sometimes includes about 2 to about 50 cage connection apertures (e.g., 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48). In some embodiments, a set of cage connection apertures includes about 4 to about 14 apertures (e.g., about eight apertures). Generally, a cage connection aperture is of any suitable shape and size sufficient to provide a chosen rate of air flow into and out of a cage, and often is circular or oval in cross section.

A cage mount support member generally includes an end aperture for each plenum, which is at the end of the cage mount support member where it connects to a side member. In some embodiments, the cage support member has a first set of support member end apertures in connection with a first plenum and a second set of support member end apertures in connection with a second plenum. The support member end aperture can have any suitable profile. In some embodiments, the support member end aperture has the same profile as the plenum to which it is connected (e.g., elliptical). Sometimes, the aperture is smaller than the cross section of a plenum (e.g., the end of the plenum includes a wall and the end aperture is in the wall) and sometimes is substantially coextensive with the cross section of the plenum (e.g., there is no wall covering the end).

In some embodiments, cage mount support member end apertures are in effective contact with, or are in air communication with, the side member end apertures such that each first support member plenum is in effective connection with each first side member plenum and each second support member plenum is in effective connection with each second side member plenum.

Sometimes, a cage mount support member includes a channel, and sometimes one or more channels are positioned between plenums. A channel can have any suitable profile. In some embodiments, a channel is substantially rectangular in profile and is between walls of the two plenums and can contain a communication medium. In some embodiments, a cover snaps over the channel.

Side Members

Side members generally are connected to one or more cage mount support members. In some embodiments, side members include plenums for the movement of air through and in and out of the rack system, and side members generally provide support for the cage mount support members. In some embodiments, there are two side members substantially perpendicular to and connected to two or more cage mount support members. In certain embodiments, side members and support members are directly and/or indirectly (e.g., effectively) connected via a gasket intermediary.

A side member may have any suitable profile, non-limiting examples of which include rectangular, cylindrical and elliptical. In some embodiments, a side of a side member is substantially rectangular. In certain embodiments, a side member includes a flat inner surface that contacts one or more cage support members and a rounded outer surface (e.g., the outer surface is convex with respect to the inner surface).

The height of a side member often is determined by the number of cage mount support members that can be connected (e.g., rows). Generally there are about 2 to about 20 rows (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 or 19 rows). In some embodiments, there are about twelve rows in a rack unit. In certain embodiments, there are about eight rows in a rack unit.

A side member generally includes one or more channels or plenums. The channels or plenums of the side member generally are independent, with substantially no air communication between the plenums. The plenums often extend substantially the entire length of a side member. In some embodiments, one or more walls (e.g., continuous or sections attached to each other) of the side member contain a first side member plenum and a second side member plenum that extend the length of the side member. The plenums generally are tubular and can have any suitable profile, non-limiting examples of which include rectangular, cylindrical are elliptical. Plenums in one side member, or among side members in a rack, can have the same or different profiles. In some embodiments, the cross section of the two plenums in a side member are substantially rectangular. Generally, the first side member plenum and the second side member plenum in a side member have end apertures. A side member end aperture can have any suitable profile. In some embodiments, the side member end aperture has the same profile as the plenum to which it is connected and is substantially rectangular. Sometimes, the aperture is smaller than the cross section of a plenum (e.g., the end of the plenum is substantially includes a wall and the end aperture is in the wall) and sometimes the aperture is substantially coextensive with the cross section of the plenum (e.g., there is no wall covering the end).

A side member generally has one or more sets of side member apertures in the wall or walls of an inner surface. A side member aperture often is in connection with a single side member plenum. In some embodiments, each side member includes a first set of side member apertures and a second set of side member apertures. One or more apertures of the first set of side member apertures often are in connection with a first side member plenum, and are in effective connection with (e.g., in air communication with) one or more apertures of a first set of support member end apertures. One or more apertures of a second set of side member apertures often are in connection with a second side member plenum and are in effective connection with (e.g., air communication with) one or more apertures of a second set of support member end apertures. Generally a set of side member apertures includes about 1 to 20 apertures (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 or 19 apertures). In some embodiments, a set of side member apertures is twelve apertures. In certain embodiments, a set of side member apertures is 8 apertures. In some embodiments, the first and second set of side member apertures are adjacent to each other and regularly spaced along the length of a side member.

The side member apertures can have any suitable profile. In some embodiments, the side member apertures have the same profile as a support member end aperture to which it is connected. In some embodiments, the side member apertures have an elliptical profile.

A side member sometimes includes one or more a channels, and in some embodiments one or more channels are positioned between plenums. A channel can have any profile. In some embodiments, a channel has a substantially rectangular profile, is between walls of two plenums and is suitably configured to contain a communication medium. In the some embodiments a side member includes a communication aperture that is in effective connection with a channel. Generally, a communication aperture is positioned between first and second side member apertures. The communication apertures can have any suitable profile. In some embodiments, the communication apertures have a substantially rectangular profile. The communication aperture often is in effective connection with a channel between the plenums in a cage mount support member.

In some embodiments, each side member includes an air connector plate at the top of the side member. In certain embodiments, an air connector plate has an aperture the can effectively connect with one of the end apertures at the upper side of a side member. In some embodiments, an air connector plate attached to a side member has an aperture in effective connection with the aperture on the upper end of a first plenum of the side member (supply plenum) and an air connector plate attached to the opposite side member has an aperture in effective connection with the aperture on the upper end of a second plenum of the side member (exhaust plenum). An air connector plate generally effectively blocks air flow through the plenum in a side member for which it has no connecting aperture, i.e., a supply air connector plate substantially blocks the second side member plenum in the side to which it is attached and a exhaust air connector plate side member plate substantially blocks the first side member plenum in for the side it is attached. Generally, a supply air connector plate and exhaust air connector plate have apertures that are in opposite orientation. In some embodiments an air connector plate functions as a mount for a modular blower unit. In some embodiments a supply air connector plate, and sometimes an exhaust air connector plate, includes a circuit board hub as described below. In certain embodiments, an air connector plate is effectively (e.g., physically and/or functionally) connected to the top of a side member through a gasket intermediary. In some embodiments, a gasket intermediary (e.g., between support members and side members, between air plate connectors and side members, the like) comprises a silicone foam rubber, and in certain embodiments, the silicone foam rubber has a 30 shore A rating. In some embodiments, the silicon foam rubber material used for gaskets is in the range of about 0.100 inches to about 0.150 inches, +/− about 0.020 inches. In certain embodiments, the silicone foam rubber gasket material is about 0.125 inches +/−0.020 inches.

In some embodiments, a side member has an optional cover on the exterior surface of the side member opposite the surface of the side member that contacts the cage support members. Generally, the cover extends essentially the entire length of a side member. The cover can be manufactured from any material suitable for constructing a rack unit. Non-limiting examples of materials used to construct a rack unit include metal alloys (e.g., sheet metal) polymers, the like and combinations of the foregoing. The cover functions to cover any communication media contained in a channel in the side member and often serves as a cosmetic feature.

In some embodiments, each side member is in contact with a gasket (e.g., gasket intermediary). A gasket often matches the geometry of the first and second plenums and often is positioned at the bottom of the side member between the side member and trolley frame tube with which it contacts. The gasket generally serves to seal the rack system when air is supplied and exhausted from the rack system. The gasket can be made of any material suitable for sealing and a non-limiting example is silicone rubber (and other non-limiting examples of gasket materials are described herein).

Cage Mount Assembly

One or more cages may be stored on or in a rack unit and any convenient configuration for storing a cage can be utilized. A cage sometimes is placed on a surface of a rack and stored for a period of time. A rack unit sometimes includes one or more cage mount assemblies useful for storing one or more cages in or on the rack unit.

Cage mount assemblies are typically positioned on the lower surface of a cage mount support member. Cage mount assemblies can be configured in any suitable manner relative to the cage mount support member. Generally cage mount assemblies may be constructed of any material suitable for engaging cages and a non-limiting example is a plastic. Non-limiting examples of rigid plastic include nylon 30% glass and non-limiting examples of non-rigid plastic include silicon rubber and silicon rubber foam. In some embodiments, cage mount assemblies are configured for attaching an upper surface of the cage mount assembly to the lower surface of a cage mount support member. In some embodiments, a cage mount assembly is configured so that the longer length of the cage mount assembly is perpendicular to the longer length of a cage mount support member to which it is attached. In certain embodiments, cage mount assemblies are regularly spaced across the transverse axis of a cage mount support member. A cage mount assembly may be fastened or mounted to a cage mount support member by any suitable connection or connector, and non-limiting examples include a threaded connector (e.g., screw), pin, an adhesive or by friction. In certain embodiments, two thread forming screws are inserted through each cage mount assembly into a cage mount support member.

A cage mount support member generally can be attached to one or more cage mount assemblies, sometimes about two to about 20 cage mount assemblies (e.g., about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 or 19 cage mount assemblies. In some embodiments, a cage mount support member has nine cage mount assemblies attached.

A corresponding mount member sometimes is located on one or more outer surfaces of a cage and is adapted to connect with a cage mount assembly located on a rack unit. In certain embodiments, a cage mount assembly comprises a guide rail adapted to receive, sometimes slideably receive, a corresponding flange or groove on or in a cage. In some embodiments, a cage mount assembly includes a guide rail positioned on a lower surface of the cage mount assembly. A guide rail often includes a stem and a first cross projection on one side of the guide rail stem and a second cross projection on the other side of the guide rail stem. The cross projections sometimes are skewed relative to each other in cross section (i.e., they are offset from one another in cross section) and sometimes the cross projections are contiguous (i.e., not offset). The cross projections often extend the length of a guide rail and often are substantially perpendicular to the guide rail stem. In certain embodiments, a cage bottom lip on a side of a cage (e.g., a flange) engages the first cross projection of the guide rail of a first cage mount assembly and the cage bottom lip on the other side of the cage (e.g., flange) engages a cross projection of the guide rail of a second cage mount assembly that is adjacent to the first cage mount assembly, in which embodiments two successive guide rails engage a single cage. In certain embodiments, a cage hangs from guide rails and is suspended below the cage mount support member. In certain embodiments, a cage is properly positioned on guide rails when a cage bottom flange is substantially in contact with and rests upon the cross projections of the guide rails of adjacent cage mount assemblies.

Cage mount assemblies often include one or more channels that accommodate a communication medium. A channel often substantially extends the length of the cage mount assembly, and in some embodiments, a channel has an end aperture at the end of the cage mount assembly. In certain embodiments, a channel contains a communication medium. In some embodiments, a channel contains SATA cable and includes a receptacle to secure the SATA cable.

A cage mount assembly sometimes includes a removable front module that attaches to the front end of a cage mount assembly. Generally, the lower portion of the front module contacts the guide rail of the cage mount assembly and the upper portion contacts the aperture of a channel of the cage mount assembly. In some embodiments, the front module includes a beveled and/or curved lip that aids in engagement of a cage with the guide rail of the cage mount assembly (e.g., the lip can function as a lead-in surface for facilitating slideable engagement of a cage with a guide rail). The front module can be a plug or can include a device and electronic components required for the device. In certain embodiments, the electronic components in the front module connect with a communication medium in the cage mount assembly. In some embodiments a front module includes a cage reader.

Modular Blower Systems

Modular blower systems are generally either air supply or air exhaust systems. In some embodiments, a modular blower system includes two or more independent assemblies that are stacked or connected in series such that air can be moved sequentially from one module to another. In some embodiments, a modular blower system includes three or more independent assemblies (i.e., independent modules) that are stacked or connected in series such that air can be moved sequentially from one module to another. The modules and assemblies may be stacked vertically or horizontally. Sidewalls of two or more or all modules often are contiguous when the modules of the blower are stacked. Edges of two or more or all modules often are contiguous when the modules of the blower are stacked.

In some embodiments, a blower system can include one or more modules that each include one or more units of the same type, such as one or more air intake unit, one or more exhaust units, one or more fan units and/or one or more filter units, for example. A module can have any suitable number of units, and in some embodiments a module can comprise about 1 to about 20 units in a suitable combination (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 or 19 units). Where a module includes two or more units of a particular unit type (e.g., fan unit), the units of the particular type can be directly connected to one another and/or there can be one or more other types of units disposed between the units of a particular type. In some embodiments, the multiple units of a particular type can be disposed in parallel or series in a module. In certain embodiments, a module can include two or more fan units attached to two or more filter units. In certain embodiments, a module can include two or more fan units in series or parallel (e.g. 2, 3, 4, 5, 6, 7, 8, 9, 10) and/or two or more filter units in series or parallel (e.g. 2, 3, 4, 5, 6, 7, 8, 9, 10). In certain embodiments, multiple modules within a blower can include more than one type of unit. For example, each of two modules can include a fan unit and a filter unit and the modules can be assembled in the blower such that the units are in the following order: fan unit—filter unit—fan unit—filter unit.

In some embodiments, a modular blower system includes modules that include an air intake or exhaust unit, a fan unit, a filter unit. In some embodiments the modular blower includes modules that include a fan unit and a filter unit. An air intake unit generally includes one or more pre-filters. A pre-filter can be made of any material that generally can capture larger particles in the air, a non-limiting example is open cell foam. In certain embodiments, a pre-filter is in the top portion of the air intake unit. In some embodiments, an air intake unit can include any suitable material configured to function as a baffle to reduce sound emitted by the fan unit. A non-limiting example of baffle material is ABS plastic.

An air exhaust unit directs air out of a modular blower system. In some embodiments, the air exhaust unit includes an outlet structure in air flow connection with the air exhaust unit through which air can exits the air exhaust unit. The outlet structure can be any suitable form for directing exhaust air out of the air exhaust unit. The air outlet structure is generally tubular and can have any suitable profile, non-limiting examples of which include rectangular, cylindrical and elliptical. In a certain embodiment the outlet structure is connected to the sidewall of the air exhaust unit. In certain embodiments, the outlet structure is perpendicular to the sidewall of the unit. In some embodiments, the outlet structure is attached to a vacuum system so that exhaust air does not enter the immediate surroundings. In certain embodiments, the vacuum system is an HVAC system. In some embodiments, an air exhaust unit can include any suitable material configured to function as a baffle to reduce sound emitted by the fan unit.

A fan unit generally includes one or more fans. In certain embodiments, one or more of the fan are counter-rotating. In some embodiments, each fan delivers air at high pressure throughout the supply plenums in the rack system. In certain embodiments, each fan is oriented to blow air into the system (supply) or each fan is oriented in the opposite orientation to draw air out of the system (exhaust). In some embodiments, there is a gasket between the bottom of the fan unit and the unit to which the fan unit is connected, typically the filter unit.

A filter unit generally can include any type of air filter, non-limiting examples include HEPA filter and charcoal filters. In certain embodiments, the filter is a HEPA filter. In certain embodiments, the filter includes a HEPA filter and a pre-filter that typically upstream of the HEPA (exhaust air first contacts the pre-filter and then the HEPA filter). In some embodiments, the filter unit includes an air channel to direct air flow into a first plenum or second plenum in a side member. In certain embodiments, the filter unit includes a pressure sensor port on the bottom of the unit for functional association with a blower pressure control board (pcb).

In some embodiments, the filter unit is attached to a blower base. The blower base generally provides support for the blower modules and houses the blower pressure control board to which the fan or fans are in effective communication. Generally, the pressure control board includes a pressure sensor. The pressure sensor typically measures the differential pressure between the system downstream of the HEPA filter and the ambient pressure. Ambient pressure is typically measured from a port in the blower base. In some embodiments, the blower base is in effective and/or physical connection to a blower control circuit board (e.g., blower controller board or blower controller).

In some embodiments a modular blower system is a supply system that includes an intake unit, a fan unit and a filter unit. In certain embodiments, ambient air first enters the intake unit and passes through a pre-filter, passes to the fan unit, then through the filter unit and exits the modular blower system. In certain embodiments, air enters the top of the intake unit in a vertically oriented assembly. In some embodiments, the modular blower system is in connection with a rack system and air that exits the modular blower system enters a first side member plenum or supply plenum. In certain embodiments a modular blower system is attached to a rack system on top of a side member. In some embodiments, attachment of a modular blower system to a rack system is by a blower base attached to a supply air connector plate attached to the rack unit.

In some embodiments a modular blower system is an exhaust system and includes an exhaust unit, a fan unit and a filter unit. In certain embodiments air first enters a filter unit, passes through a fan unit, then through an air exhaust unit to exit the modular blower system. In certain embodiments, the filter unit includes a HEPA filter and a pre-filter. In some embodiments, a modular blower system is in connection with a rack system and air enters the modular blower system from a second side member plenum (exhaust plenum) into a filter unit. In certain embodiments, the modular blower system is attached to a rack system on top of a side member. In some embodiments, attachment of a modular blower system to a rack system is by a blower base attached to an exhaust air connector plate attached to the rack unit.

In some embodiments, a supply modular blower system and an exhaust modular blower system are attached to a rack system, the supply modular blower system is attached on the top of a side member and the exhaust modular blower system is attached on top of the opposite side member.

In some embodiments, a modular blower system can have any number of additional modules added, including additional fan units and filter units. Generally, these modular can be added in any order to an exiting set of modules.

Supply blower systems can be constructed in left and right orientations which are essentially mirror images of each other. The air intake unit and fan unit are the same. The filter unit, base and air connector plate have left and right orientations. Exhaust blower systems can be constructed in left and right orientations which are essentially mirror images of each other. The air exhaust unit and fan unit are the same. The filter unit, base and air connector plate have left and right orientations. In general for a single rack unit that have blower systems attached, a right orientation supply blower system is placed on one side member and a right orientation exhaust blower in placed on the opposite side member. Typically, for two rack units attached to a trolley assembly that have blower systems attached, a right orientation supply blower system is placed on one side member of a first rack unit and a left orientation supply blower is placed on the adjacent side member of the second rack unit. The opposite side members of the two racks have a right orientation exhaust blower placed on the first rack unit and a left orientation exhaust blower placed on the second rack unit.

In some embodiments modular blowers are connected to a power supply. In certain embodiments, power is distributed from a power supply to a first modular blower unit and from the first modular blower unit to a second modular blower unit. The first modular blower unit can be an exhaust unit or a supply unit. In some embodiments, with two rack systems, power is distributed from a power supply to a first modular blower unit on each rack system and then from the first modular blower units on each rack system to a second modular blower on the same rack system. The first modular blower units can be exhaust units or supply units. In certain embodiments, the first modular blower units are exhaust blower units and the second modular blower units are supply blower units.

Each blower unit is of a suitable shape to permit stacking, airflow and filter functions. Non-limiting examples of blower unit bodies include tubular, structures comprising parallel sides, one or more bevels, tapers and/or flairs. Non-limiting examples of a cross section for blower unit bodies include circular; oval; rectangular; square; rhomboid; variants of rectangular, square and rhomboid geometries having bevels, curved edges, curved corners, and bevels; the like; and combinations of the foregoing. Each blower unit is constructed from one or more suitable materials, non-limiting examples of which include polymers (e.g., polypropylene (PP), polyethylene (PE), high-density polyethylene, low-density polyethylene, polyethylene teraphthalate (PET), polyvinyl chloride (PVC), polyethylenefluoroethylene (PEFE), polystyrene (PS), high-density polystryrene, acrylnitrile butadiene styrene (ABS) copolymers and the like and applicable recyclable versions thereof), metals (e.g., steel, aluminum, other metals or alloys), the like and combinations thereof. Each unit sometimes is connected to an adjacent unit without fasteners (e.g., by a substantially loose fit or friction fit), by a harness, or by one or more fasteners, in certain embodiments. Non-limiting examples of fasteners include reversible, non-reversible, threaded, non-threaded, deflectable, non-deflecting, interference fit, male and female fasteners, the like and combinations of the foregoing. Fasteners may be located in or on any suitable surface of a blower unit and may be on or in an interior or exterior surface. A blower assembly may include one or more connectors between one or more sets of adjacent units. A connector in some embodiments can be flexible, semi-flexible, substantially flexible, deformable, semi-deformable, substantially deformable, rigid, substantially rigid or semi-rigid. A connector may function as a seal between adjacent units in certain embodiments. A connector sometimes is a sleeve that covers one or more edges of a unit. In certain embodiments, a connector is a gasket.

In some embodiments, blower units can be detached from a rack unit and re-attached. For example if a rack unit is to be washed or autoclaved, blower units may be detached prior to washing or autoclaving and then reattached.

Modular blower systems 600, 700 include base 620, 621 (supply) and, 720, 721 (exhaust). Bases 620, 621, 720, 721 are configured to slidingly engage filter units 606, 607, 706, 707, respectively and differ from each other in placement of air channel opening and placement electronics for monitoring pressure, in certain embodiments. In some embodiments, bases 620, 621, 720, 721 also include stacking support protrusion 622, 722, which is configured to slidingly engage air connector plate blower support boss 590 to attach and secure blower 600, 700 to cage rack 500 via air connector plates 584, 586. In certain embodiments bases 720, 721 also include stabilizing connectors 727. Stabilizing connectors 727 are configured to functionally associate with one or more connectors on rack 500 thereby securing and stabilizing blower 700. In certain embodiments, stabilizing connectors 727 include two indents in to which brackets on the blower stand clip. In some embodiments, stabilizing connectors 727 helps reduce or eliminate vibration, and in certain embodiments, stabilizing connectors 727 help reduce or eliminate vibration in conjunction with a gasket intermediary. Without being limited by theory, stabilizing connectors 727 may help reduce or eliminate vibration by minimizing lateral movement during blower operation.

Modular blower units 602, 702, 604, 704, 606, 607, 706, 707 on blower 600, 700 are joined using 4 long screws. Screw heads are retained in air intake unit 602 and/or air exhaust unit 702. Screws pass through fan unit 604,704 and are secured into brass threaded inserts in filter unit 606, 607, 706, 707 and base 620, 621, 720, 721. Gaskets are utilized between each modular blower unit, which gaskets are compressed when the screws are tightened to generate an air-tight seal between the assembled units. Blower base 620, 621, 720, 721 is secured onto the bottom of HEPA filter unit 614, 714 with 4 screws. Modular blower system 600, 700 is properly aligned, for mating with cage electronics, on top of cage rack 500 using 2 metal air connector plate mounting pins 588, located on the front of air connector plate 584, 586 and a large plastic boss or protrusion 590 located on the back of air connector plate 584, 586. Pins 588 and boss 590 are included as part of air connector plate 584, 586 and air connector plates 584, 586 are mounted to the rack. In some embodiments, modular blower system 700 is properly aligned for mating with cage electronics, on top of cage rack 500, using two metal air connector plate mounting pins 588′ (see FIG. 74) located on the front of air connector plate 584, 586. Mounting pins can be metal or any other suitable material, in some embodiments. Embodiments comprising metal air connector plate mounting pins 588′ sometimes do not include a plastic boss or protrusion 590 located on the back of air connector plate 584, 586. In some embodiments, pins 588′ are included as part of air connector plates 584, 586 and air connector plates 584, 586 are mounted to the rack.

Alignment of blower 600, 700 utilizing pins 588′ and/or pins 588 and boss or protrusion 590 enables proper attachment of blower 600, 700 to cage rack 500 air connector plate 584, 586 prior to engagement of the blind mate connector on the blower (not shown) comes into contact with blind mate connector 908 on the rack mounted circuit board hub 900. Proper alignment of blower 600, 700 and air connector plate 584, 586 ensures that the connectors are not damaged when engaged.

Pins 588, 588′ also act as a locking feature for blower 600, 700. When blower 600, 700 is lowered over pins 588, 588′, the pins deflect a set of spring plungers (e.g., spring loaded connectors) 618, 718 that lock the blower into place when spring loaded connectors 618, 718 return to their non-deflected position and engage a notch in pins 588. Spring plungers 618, 718 are housed in HEPA filter unit 614, 714. Pins 588′ are configured to allow proper orientation by virtue of being non-identical, thus mating can only occur if the pins are aligned with the correct mounting holes of the modular blower system base.

With reference to FIGS. 26-30, and 37, modular blower systems 600, 700 are powered by power supply 740. A schematic wiring diagram is shown in FIG. 37. Power supply cables 742 are routed from power supply 740 to the circuit board hub 900 in effective connection with exhaust blower 700, and from circuit board hub 900 in effective connection with exhaust blower 700 to the circuit board hub 900 in effective connection with supply blower 600, in some embodiments. FIG. 37 schematically illustrates the wiring for a double rack. The wiring for a single rack eliminate cables 742 to the second set of blowers. Each power supply cable includes four 16 gauge (e.g., 16 GA) wires for power and two 22 GA wires for communication. Power supply cables 742 power two blowers at one end of rack 500. These cables are routed from the power supply box to Deutsch receptacle 906 on rack 500 circuit board hub 900. Power is distributed from blowers 700 to blowers 600 at the other end of cage rack 500 through a set of two 14 GA wires that are disposed in channel 540 of the topmost support member 502. In some embodiments, cables 742 are configured for high temperature resistance and/or operation (e.g., can be autoclaved, can be used at elevated temperatures and the like), and in certain embodiments cables 742 are not configured for high temperature resistance and/or operation. In some embodiments where cables are configured to be autoclaved, electronics, wiring or electronics and wiring are sealed or enclosed to minimize or eliminate exposure to moisture. In certain embodiments, communication channels in side and/or support members are configured to minimize or eliminate exposure of communication media to moisture. In some embodiments, the 22 GA communication wires are carried using the same channels are the 14 GA wires.

Air Flow

Generally, air flows throughout the rack system from a supply blower through the first plenums in the side members and the first plenums in the cage support members, through the orifices of the cage protrusion connector assemblies connected to the first set of cage connection apertures and into the orifices of a first set of cage protrusions in the cage lids and into cages. Generally, air is drawn out of the cages through a second set of cage protrusions in the cage lids, through the orifices of cage protrusion connector assemblies connected to a second set of cage connection apertures, through the second plenums of the cage support members to a second plenum of a side member connected to an exhaust blower and out of the rack. The air generally flows in a circuit from the supply portion of a rack through the cages to the exhaust portion of the rack.

In some embodiments, the rack is configured to, when positive air pressure is supplied to the first plenum of a side member, direct air from the first plenum of a side member to a first set of side member apertures of a side member to a set of support member end apertures to the first support member plenums and through the first set of cage connection apertures.

In certain embodiments, the rack is configured to, when negative air pressure is supplied to the second plenum of a side member, direct air through the second set of cage connection apertures to the second support member plenums to a second set of support member end apertures to a second set of side member apertures of a side member and to the second plenum of a side member.

In some embodiments, a blower is in effective connection with an aperture at the top of the first side member, an aperture at the top of the second side member, or apertures at the top of the first side member and the second side member. Generally, a supply blower is in effective connection with only one of the two plenums in a side member. The plenum in effective connection with the supply blower is typically designated as a supply plenum. The other plenum on that side member is typically designated as an exhaust plenum. In some embodiments, an exhaust blower is in effective connection with only one of the two plenums in the other side member. The plenum in effective connection with the exhaust blower is typically designated as an exhaust plenum. The other plenum on that side member is typically designated as a supply plenum. Generally, supply and exhaust plenums are substantially isolated from each other such that essentially no air is directly exchanged between the two plenums. Each supply plenum of the side members generally is in effective connection with only one set of plenums in the cage support members, also designated as supply plenums. Each exhaust plenum of the side members generally is in effective connection with only one set of plenums in the cage support members, also designated as the exhaust plenums. In such embodiments, the supply plenums and the exhaust plenums are in effective fluid or air connection as air passes in and out of cages. The supply plenum of each cage mount support is in effective fluid or air connection with a cage through a first cage connection aperture which is connected to a supply cage protrusion connector assembly. The exhaust plenum of each cage mount support is in effective fluid or air connection with a cage through a second cage connection aperture which is connected to an exhaust cage protrusion connector assembly.

In some embodiments the pressure across a first support member plenum varies less than about 5%. Generally, air pressure is measured at the cage protrusion connector assemblies. Without being limited by theory, the configuration of the supply plenums allowing for air flow in side member plenums on both sides of the cage support member plenums may contribute to achieving this uniform pressure.

In some embodiments, air flow in the first support member plenum and the second support member plenum is transverse to the air flow across the bottom of one or more cages. Generally air flows through support member plenums that extend substantially the entire length of the support member. Cages are generally inserted in the rack unit such that the longer length of a cage is substantially perpendicular to the longer length of the support member to which a cage is mounted. Generally, air enters a cage from a first support member plenum (supply plenum) through a cage connector protrusion assembly that is engaged with a first cage protrusion in the cage lid (located toward the front of the cage). Supply air generally flows downwards and across the bottom of the cage upwards and out of the cage through a second cage protrusion in the cage lid located toward the rear of the cage. Exhaust air generally flows through the cage connector protrusion assembly that is engaged with a second cage protrusion in the cage lid into a second support member plenum (exhaust plenum) and through the second support member plenum along the length of the support member. Exhaust plenums often extend substantially the entire length of the support member.

Some embodiments are shown in FIGS. 26-30, and 37-46. Rodent containment cage rack 500 sometimes is configured to, when positive air pressure is supplied to the first side member plenum 522 of side member 504 direct air from the first side member plenum 522 of side member 504 to the first set of side member apertures 526 of a side member 504 to a set of support member end apertures 518 to the first support member plenums 508 and through the first set of cage connection apertures 512. Cage rack 500 sometimes also is configured to, when negative air pressure is supplied to the second side member plenum 524 of side member 506, direct air through a second set of cage connection apertures 514 to second support member plenums 510 to a second set of support member end apertures 520 to a second set of side member apertures 528 of side member 506 and to the second side member plenum 524 of side member 506.

Positive air pressure is provided by modular supply blower system 600, which is in effective connection with cage rack 500, in some embodiments. Negative air pressure is provided by modular exhaust blower system 700, which is in effective connection with cage rack 500, in certain embodiments. In certain embodiments, rack 500 includes modular supply blower system 600 and modular exhaust blower system 700. Blower 600, 700 is in effective connection to first side member upper aperture 532, second side member upper aperture 534, or first side member upper aperture 532 and second side member upper aperture 534.

With reference to FIGS. 22-23, 30, 35, 52-54, and 59-61, rack 500 also includes cage protrusion connection assembly 800, 800′ each assembly including nozzle 834 in effective connection with the cage connection apertures 512, 514. In some embodiments, cage rack 500 includes cages 20. Air enters each cage 20 effectively through an aperture of the first set of cage connection aperture 512 and exits cage 20 effectively through an aperture of the second set of cage connection apertures 514 in certain embodiments. Cages 20 are engaged with cage protrusion connection assemblies 800, 800′ in effective connection with the first set of cage connection apertures 512 and the second set of cage connection apertures 514, in some embodiments. Air flow in the first support member plenum 508 and the second support member plenum 510 generally is transverse to the air flow across the bottom of the cages 20.

With reference to FIGS. 26, 27, 38, and 48-51 in some embodiments, blower 600 is in effective connection with rack 500 via supply air connector plate 584. In certain embodiments, blower 700 is in effective connection with rack 500 via exhaust air connector plate 586. Cage rack 500 also includes a first air connection plate 584 including an aperture 585 in effective connection with an upper end aperture 532 of a first side member plenum 522 of side member 504 and also includes a second air connection plate 586 including aperture 587 in effective connection with upper end aperture 534 of a second side member plenum 524 of opposite side member 506, in some embodiments. Air connector plates 584 and 586 also include air connector plate mating pins 588, 588′, and in some embodiments, blower support protrusion 590 and power supply support recesses 592. Air connector plate mating pins 588 in conjunction with blower support protrusion 590 secure and support blower 600, 700 on cage rack 500 and also allow for proper alignment of blower 600, 700 with side member upper apertures 532, 534, in some embodiments. In certain embodiments, air connector plate mating pins 588′ secure and support blowers 600, 700 on cage rack 500 and also allow for proper alignment of blowers 600, 700 with side member upper apertures 532, 534, in some embodiments. Power supply support recesses 592 secure and support power supply 740 adjacent to blower 700 (see FIGS. 48-49, and 51) Air connector plates 584, 586 are permanently secured to rack 500, in some embodiments, and in certain embodiments air connector plates 584, 586 are permanently secured to rack 500 via a gasket intermediary.

Cage Connector Assemblies

A cage connection aperture in a cage mount support member often is in effective connection with a cage connector assembly that facilitates airflow between a cage and a rack member. In some embodiments, each cage connection aperture is in effective connection with one cage connector assembly. A cage connector assembly can be directly connected to a cage connection aperture, in certain embodiments. A cage connector assembly sometimes is indirectly connected to and associated with a cage connection aperture, and often is connected to a cage mount support member in proximity to a cage connection aperture, in certain embodiments. In some embodiments, a cage includes one or more protrusions (e.g., an upward extending protrusion in the lid of a cage), where each protrusion includes an aperture that allows for air flow into the cage or from the cage. In the latter embodiments, a cage connector assembly in a rack can be referred to as a “cage protrusion connector assembly.”

A cage connector assembly can be of any suitable configuration for facilitating airflow between a rack member and a cage. In some embodiments a cage connector assembly includes a cage connector component, a nozzle and one or more seals (e.g., gaskets). The cage connector component in some embodiments includes a body and an orifice in the body. A cage connector can be of any suitable geometry for interaction with a cage member (e.g., a cage protrusion) and non-limiting examples of a body surface or cross section include circular; oval; rectangular; square; rhomboid; variants of rectangular, square and rhomboid geometries having bevels, curved edges and/or curved corners; the like; and combinations of the foregoing. An orifice can be of any suitable shape, non-limiting examples of which are circular and oval. A circular or substantially circular orifice can be defined by any suitable radius, which radius often is selected to allow for the cage connector assembly to interact with a cage member. An orifice can be defined by a radius that permits insertion of a portion or all of the conical into a cage connector assembly interior. In some embodiments, the radius of a cage connector component orifice is about 0.05 inches to about 0.70 inches (e.g., about 0.06, 0.07, 0.08, 0.09, 0.10, 0.20, 0.325, 0.350, 0.375, 0.40, 0.50 or 0.60 inches). A cage protrusion in some embodiments is a conical protrusion comprising an aperture at its apex, or other protrusion comprising a taper and an aperture.

A cage connector component of a cage connector assembly can be manufactured from one or more suitable materials. A cage connector component sometimes is manufactured from one or more polymers (e.g., described herein), and often is rigid or substantially rigid, thereby contributing to a shell or shell-like structure of the cage connector component. In some embodiments, the cage connector component is manufactured from nylon and is about 10% to about 50% glass filled (e.g., about 15%, 20%, 25%, 30%, 35%, 40% or 45% glass filled). A cage connector often is manufactured from a material that can withstand washing and/or autoclave conditions (e.g., repeated exposure to heat, humidity, spraying and/or rinsing).

In certain embodiments, a cage connector assembly includes one or more fasteners extending from a first surface of the body. The one or more fasteners often are configured to engage fastener counterparts of one or more other assembly components (e.g., gasket or gaskets), and in embodiments that include two or more fasteners, the fasteners sometimes are disposed around the body perimeter and/or around the orifice. Any suitable fastener can be utilized, non-limiting examples of which include reversible, non-reversible, threaded, non-threaded, deflectable, non-deflecting, male, female, the like and combinations of the foregoing. In some embodiments, a fastener is a barbed fastener that optionally can be deflected. A fastener generally is configured to fasten one or more assembly components and sometimes is configured to also engage a cage connector assembly with cage mount support member.

In certain embodiments, a cage connector includes a member that aligns other components of the cage connector assembly. Any suitable alignment member can be utilized, non-limiting examples of which include a tab, pin and rod.

A cage connector component does not directly engage a portion of a cage in some embodiments, and in certain embodiments, a portion of a cage connector component directly engages a portion of a cage (e.g., when the cage is moved into its destination, or docked position, for use in the rack). In some embodiments, a cage connector component is configured to position a cage in a rack. Such a cage connector component often positions a cage in a rack in concert with other rack members (e.g., guide rails) and sometimes one or more cage connector components are responsible primarily for positioning a cage in a rack (e.g., limiting rearward movement of the cage).

A cage connector component sometimes includes a cage engagement member that contacts a portion of a cage. A cage engagement member sometimes is referred to as a “cage protrusion engagement member” where the cage includes a protrusion that interacts with a cage connector assembly. A cage engagement member often includes a surface, sometimes a projected surface, that conforms to and reversibly mates with (e.g., rests against or contacts) a surface of a cage (e.g., a cage protrusion), and such a surface in a cage connector component sometimes is configured to position a cage in a rack. The geometry of a cage engagement member often is determined by the corresponding geometry of a cage member with which the cage engagement member interacts. Non-limiting examples of a cage engagement member geometry and/or surface include flat, curved, tapered, flared, frustrum, conical, the like, and combinations and portions thereof. In non-limiting examples, a cage protrusion that interacts with a cage connector component is substantially conical, and the corresponding surface of the cage engagement surface in cage connector subcomponent (e.g., the projected surface) is curved with a substantially similar or substantially identical radius and taper as the corresponding surface of the conical protrusion of the cage with which it contacts. In some embodiments, a cage engagement member (e.g., a projected surface) of a cage connector component extends from a second surface of the cage connector component opposite the first side of the component, and can extend any suitable maximum length from the surface of the second side (e.g., about 0.01 to about 3 inches (e.g., about 0.05, 0.1, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5 or 2 inches; or about 0.094 or about 0.095 inches)). An interaction with a cage member (e.g., cage protrusion) with a surface (e.g., a projected surface) of a cage connector assembly is described in greater detail hereafter.

A cage connector assembly generally comprises a connector gasket (e.g., cage protrusion connector gasket) in some embodiments. A connector gasket generally is configured to sealing connect with a cage connector component and can be of any suitable geometry, non-limiting examples of which include circular; oval; rectangular; square; rhomboid; variants of rectangular, square and rhomboid geometries having bevels, curved edges and/or curved corners; the like; and combinations of the foregoing. In some embodiments, the term “sealing connection” as used herein refers to an air-tight seal or substantially air-tight seal between two structures.

A connector gasket can be manufactured from a suitable material, which material often is flexible, semi-flexible, substantially flexible, deformable, semi-deformable and/or substantially deformable. Non-limiting examples of one or more materials that can be included in a connector gasket include plastics, thermoplastics, elastomers, thermoplastic elastomers (TPEs), thermoplastic vulcanizates (TPV; SANTOPRENE TPV), thermoplastic polyurethane (TPU), thermoplastic olefins (TPO), polysulfide rubber, ethylene propylene rubber (e.g., EPM, a copolymer of ethylene and propylene), ethylene propylene diene rubber (e.g., EPDM, a terpolymer of ethylene, propylene and a diene-component), epichlorohydrin rubber (ECO), polyacrylic rubber (ACM, ABR), silicone rubber (SI, Q, VMQ), fluorosilicone Rubber (FVMQ), fluoroelastomers (e.g., FKM, and FEPM, VITON, TECNOFLON, FLUOREL, AFLAS and DAI-EL), perfluoroelastomers (e.g., FFKM, TECNOFLON PFR, KALREZ, CHEMRAZ, PERLAST), polyether block amides (PEBA), chlorosulfonated polyethylene (CSM, e.g., HYPALON), ethylene-vinyl acetate (EVA), synthetic polyisoprene (IR), butyl rubber (copolymer of isobutylene and isoprene, IIR), halogenated butyl rubbers (chloro butyl rubber: CIIR; bromo butyl rubber: BIIR), polybutadiene (BR), styrene-butadiene rubber (copolymer of polystyrene and polybutadiene, SBR), nitrile rubber (copolymer of polybutadiene and acrylonitrile, NBR; Buna N rubbers), hydrogenated nitrile rubbers (HNBR, THERBAN and ZETPOL), chloroprene rubber (CR, polychloroprene, NEOPRENE, BAYPREN) and the like. Non-limiting examples of TPEs include styrenic block copolymers, polyolefin blends, elastomeric alloys, thermoplastic polyurethanes, thermoplastic copolyester and thermoplastic polyamides. Examples of TPE products from the block copolymers group are STYROFLEX (BASF), KRATON (Shell Chemicals), PELLETHANE (Dow chemical), PEBAX, ARNITEL (DSM), HYTREL (Du Pont) and more. Non-limiting examples of commercially available elastomeric alloys include SANTOPRENE (in-situ cross linked polypropylene and EPDM rubber; Monsanto), GEOLAST (Monsanto) and ALCRYN (Du Pont). A connector gasket often is manufactured from a material that that can withstand washing and/or autoclave conditions (e.g., repeated exposure to heat, humidity, spraying and/or rinsing).

A connector gasket is of a suitable thickness to permit sealing engagement of a cage member (e.g., cage protrusion) to a cage connector assembly. A connector gasket can have a nominal, average, mean, maximum or minimum thickness of about 0.01 inches to 1.0 inch (e.g., about 0.02, 00.3, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 inches thick). In some embodiments, the connector gasket has a minimum thickness of about 0.02 inches to about 0.07 inches (e.g., about 0.03, 0.04, 0.05 or 0.06 inches; or about 0.047 inches) and a maximum thickness of about 0.1 to about 0.2 inches (e.g., 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18 or 0.19 inches; or about 0.156 inches). A connector gasket generally includes an orifice that often is concentric with the orifice in a cage connector component. The orifice in a connector gasket can be of any suitable shape, non-limiting examples of which are circular and oval. A circular or substantially circular orifice can be defined by any suitable radius, which radius often is selected to allow for the connector gasket to sealing engage with a cage member. In embodiments where the cage member is a conical protrusion, for example, an orifice in the connector gasket can be defined by a radius that permits insertion of a portion or all of the conical protrusion into a cage connector assembly interior, and allows for sealing connection of the connector gasket to the conical protrusion. In some embodiments, the radius of the gasket orifice is about 0.20 to about 0.25 inches (e.g., about 0.21, 0.22, 0.23 or 0.24 inches; or about 0.227 inches). A connector gasket may include an annular flange disposed around the gasket orifice configured to permit sealing attachment of the gasket to a cage member (e.g., cage projection). An annular flange can have a shape and surface that permits sealing attachment of the gasket to a cage member, non-limiting examples of which surface include flat, curved, tapered, flared, frustrum, conical, the like, and combinations and portions thereof. A connector gasket orifice may include, in some embodiments, an annular bevel disposed around the orifice.

A connector gasket may include an alignment feature that permits alignment of the gasket with the cage connector component (e.g., a bore configured to receive a pin in the cage connector component). A connector gasket, in some embodiments, may include one or more fasteners adapted to fasten to one or more fasteners in the cage connector component (non-limiting examples of fasteners are described above with respect to the cage connector component). In some embodiments, a fastener in a connector gasket is one or more slots or channels disposed near or around the gasket orifice configured to receive a fastener in a cage connector component of the assembly. In certain embodiments, a connector gasket includes one or more alignment features for a nozzle component of a cage connector assembly, non-limiting examples of which include grooves, apertures, pins, tabs, the like and combinations thereof.

A connector gasket is in sealing connection with a nozzle component of a cage connection assembly, in some embodiments. A nozzle is of any shape suitable to permit airflow from a rack to a cage and/or from a cage to a rack, and non-limiting examples of the shape of a nozzle body include substantially cylindrical structures or other structures having a circular, oval, rectangular, square or rhomboid cross-section, and a wall or walls that are parallel, tapered or flared and optionally include a bevel, curved edge, taper, flair, and the like, for example. A nozzle generally includes one or more orifices through which air may flow from a cage to a rack or from a rack to a cage. A nozzle can include any suitable number of orifices (e.g., about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 or more orifices). In embodiments where a nozzle includes one orifice, the orifice often is concentric with the orifice of a connection gasket and cage connector component of the assembly. Where a nozzle includes two or more orifices, the orifices may be arranged in any suitable configuration to permit airflow between a cage and a rack. In certain embodiments, two or more orifices are arranged regularly on a nozzle surface (e.g., the midpoints of the orifices are substantially equidistant from one another); sometimes are arranged regularly around a center-point of a nozzle surface (e.g., the distance between each orifice midpoint to the nozzle surface center-point is substantially the same for two or more or all of the orifices in the nozzle), and/or sometimes are arranged regularly around the perimeter of a nozzle surface.

A nozzle orifice may include an annular flange disposed around the orifice, which flange often extends towards the connector gasket and the cage connector component. A nozzle orifice may be in association with a bushing in some embodiments. A bushing may be manufactured from any suitable material, non-limiting examples of which include a metal (e.g., brass) or polymer or the like and combinations of the foregoing. A bushing may be flush-mounted with a nozzle in some embodiments, and in certain embodiments, a nozzle may be cast with an integrated bushing (e.g., polymer of the nozzle may cover the bushing). The effective radius of a nozzle orifice (e.g., with or without a bushing) is selected to permit suitable airflow and/or air pressure from a rack to a cage or from a cage to a rack. In some embodiments, the radius of a nozzle is about 0.005 to about 0.50 inches (e.g., about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3 or 0.4; about 0.344 inches) and the radius of a bushing orifice sometimes is about 0.005 inches to about 0.1 inches (e.g., about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09; or about 0.079 inches).

A nozzle may include an annular beveled surface, or an annular curved surface defined by a radius, in conjunction with a top and/or bottom surface of the nozzle. In some embodiments, the edge of the beveled surface or curved surface may be interrupted by a cylindrical protrusion that substantially defines a portion or all of an orifice perimeter (e.g., where an orifice is disposed towards the outer perimeter of a nozzle surface). A cylindrical protrusion in some embodiments is substantially circular in cross section, the cross section sometimes is circular or oval, and the sides of a cylindrical protrusion sometimes are substantially parallel or include or consist of a bevel, flair or taper. In the latter embodiments, the cylindrical protrusion can include an edge and the edge can meet another edge of the bevel at a corner on the exterior of the nozzle. The cylindrical protrusion also may project from an interior surface of the nozzle in some embodiments, and such a cylindrical protrusion may comprise a rib that projects from all or a portion of the cylindrical protrusion.

An orifice perimeter may be in proximity to a rib that projects from (i) a nozzle surface or surfaces pierced by the orifice, (ii) a cylindrical protrusion, or (iii) a combination of (i) and (ii), in some embodiments. A rib may be of any size and geometry that causes disruption in flow at the nozzle surface from which the rib extends, in some embodiments. A rib may be of any suitable profile (e.g., edge), and the profile sometimes is linear, curved, zigzag, S-shaped, J-shaped or T-shaped. A rib profile (e.g., edge) sometimes is semi-circular and the radius of the inner wall of the rib facing an orifice sometimes is substantially the same as the radius of the orifice (e.g., the inner wall of the rib is substantially coextensive with the orifice perimeter), and sometimes the radius of the inner wall of the rib facing an orifice is larger than the radius of the orifice (e.g., the inner wall of the rib is offset from the orifice perimeter). Whether or not the rib is substantially coextensive with or offset from the orifice perimeter, a rib can circumscribe about 10% to about 100% of the orifice perimeter (e.g., about 20%, 30%, 40%, 45%, 50%, 55%, 60%, 70%, 80% or 90% of the orifice perimeter) in some embodiments. A rib can project from a nozzle surface or projected cylinder junction any suitable distance, which distance may be uniform or varied (e.g., stepped or gradual increases or decreases in rib height). A rib can project from a nozzle surface and/or from a projected cylinder junction a maximum distance of about 0.005 inches to about 0.5 inches (e.g., a maximum rib height of about 0.006, 0.007, 0.008, 0.009, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.15, 0.20, 0.25, 0.30, 0.40 or 0.45 inches) in some embodiments. In embodiments where a nozzle includes a rib that projects from each or two nozzle surfaces or projected cylinder junction (e.g., on a nozzle exterior and on a nozzle interior) the ribs can project from a nozzle surface and/or from a projected cylinder junction the same or different maximum distance.

A nozzle can be manufactured from any suitable material, non-limiting examples of which include rigid and substantially rigid polymers (e.g., nylon) that optionally may be impregnated, mixed or coated with another material (e.g., about 10% to about 50% glass filled nylon). A nozzle may include one or more alignment features that facilitate alignment with a connector gasket, as described above (e.g., tabs or other alignment features).

A cage connector assembly also may include a mount seal or mount gasket (also referred to herein as a “nozzle gasket”) that permits sealing connection of the cage connector assembly to a cage mount support member. A mount gasket can be of a suitable geometry to permit such a sealing connection, non-limiting examples of which include circular; oval; rectangular; square; rhomboid; variants of rectangular, square and rhomboid geometries having bevels, curved edges and/or curved corners; the like; and combinations of the foregoing. A mount gasket is of a suitable thickness to permit sealing engagement of a cage connector assembly to a cage mount support member. A connector gasket can have a nominal, average, mean, maximum or minimum thickness of about 0.01 inches to 0.1 inch (e.g., about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09 inches thick). In some embodiments the maximum thickness of the connector gasket is about 0.063 inches. A mount gasket is manufactured from a suitable material, examples of which are provided above with respect to the connector gasket. A mount gasket may include an alignment feature that permits alignment of the gasket with the cage connector component (e.g., a bore configured to receive a pin in the cage connector component). A mount gasket generally includes an orifice that often is concentric with the orifice in a cage connector component, connector gasket and/or nozzle. The orifice in a mount gasket can be of any suitable shape, non-limiting examples of which are circular and oval. In some embodiments, the radius of the mount gasket orifice is about 0.1 inches to about 1.0 inches (e.g., about 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 or 0.9 inches). The inner surface of the orifice of the mount gasket often is in contact (e.g., sealing contact) with a surface of the nozzle in the cage connector assembly.

When the mount gasket is positioned in a cage connection assembly, the perimeter of the orifice in the mount gasket may be juxtaposed with one or more fasteners of the cage connector component in an orientation that permits the one or more fasteners to position and/ore secure the mount gasket in the assembly. In certain embodiments, the one or more fasteners of the cage connector component extend beyond the proximal surface of the mount gasket such that the same one or more fasteners can facilitate connection of the cage connector assembly to a cage mount support member (e.g., connected via machined slots or holes in the cage mount support member). In certain embodiments, one or more fasteners other than the one or more fasteners of the cage connector component can be utilized to mount the cage connector assembly to a cage mount support member. A cage connector assembly may be mounted to a wall surface of a cage mount support member, in some embodiments, and in certain embodiments, a cage connector assembly may be mounted within a wall recess or boss in a cage mount support member. When mounted to a cage mount support member, the orifice of a nozzle (e.g., effective orifice (e.g., bushing orifice) can be in effective connection with (e.g., in proximity to; in air communication with), or in direct connection with, a cage connector aperture in the cage mount support. A rack may include one, two, three, four or more cage connector assemblies for each cage docking site in the rack (i.e., one cage can connect to the rack at each cage docking site).

A cage connector assembly often is configured to (i) in part facilitate engagement of a cage to a rack, (ii) in part position a cage in a rack, and (iii) facilitate airflow into a cage from a rack or from a cage to a rack. In certain embodiments, a rail guide lead-in member is engaged by a cage flange by a user and the cage is translated by the user towards the rear of a rack on rail surfaces. During this translation, a side surface of a cage protrusion projecting from the top of the cage can engage a lead-in surface of a cage protrusion connector component in a cage protrusion connector assembly. Continued translation of the cage towards the rear of the rack often causes the cage protrusion to translate downward (e.g., deflect downward) and the lid of the cage to flex. Further translation of the cage towards the rear of the rack causes a top terminus of the cage protrusion side surface to move past the orifice edge of the cage protrusion connector component and the cage protrusion can translate upwards. In some embodiments, the cage protrusion springs upwards and the cage lid flexes. Engagement of the cage protrusion often results in a portion of the cage protrusion being inserted within the interior of the cage protrusion connector assembly. In some embodiments, a portion of a cage protrusion connector gasket is in sealing connection with a portion of a cage protrusion side surface after the cage protrusion translates upwards and a portion of it is within the interior of the cage protrusion connector assembly.

Contact of the cage protrusion connector gasket with a portion of the cage protrusion may be sufficient to position the cage in the rack and facilitate airflow between the rack and the cage. In some embodiments, a member of the cage protrusion connector assembly includes a surface that contacts a portion of a cage protrusion surface and interferes with further translation of the cage towards the rear of the rack. In certain embodiments, a cage protrusion connector component includes a projected surface that rests against a portion of a cage protrusion surface and functions as a positive stop by interfering with further translation of the cage towards the rear of the rack. In some embodiments, such a positive stop in the cage protrusion connector assembly functions as the sole stop that interferes with further translation of the cage towards the rear of the rack (e.g., there are no stops in a cage guide rail on a rack that interferes with rearward translation of a cage. Some or all of the cage connector assemblies in a rack comprise a positive stop, in certain embodiments.

After a cage projection has been engaged in its destination, or docked position, for use in a rack, the cage may be disengaged by reversing the engagement process described above. A cage can be engaged into, and disengaged from, its destination for use in a rack multiple times.

Controller Boards

Cage rack controller boards generally provide information for power distribution, air flow and/or cage configuration, provide a conduit for communication between various cage rack components, and in some embodiments provide a user interface for entry of information pertinent to operation of the cage rack in a given configuration. In some embodiments a cage rack can include any suitable number of controller boards and/or circuit board hubs, and in certain embodiments a cage rack includes a master rack controller functionally associated any number of controller boards and/or circuit boards or circuit board hubs in a suitable combination (e.g., 3, 4, 5, 6, 7, 8, 9, 10, or more circuit board hubs and/or controller boards, including a master controller). Cage racks described herein often have 1 blower controller board for each modular blower system in effective communication with a cage rack. Cage racks described herein generally include up to 1 rack mounted circuit board hub for each modular blower system in effective connection with the cage rack. Cage racks described herein typically include a rack controller (e.g., hand held controller, rack mounted controller, master controller, user control interface), which is operably connected to the blower control boards and circuit board hubs, and functions to (i) send and/or receive data, fan curves, user input information, (ii) interpret data received from other control/circuit boards and/or user input, and (iii) store information about rack configuration, ambient pressure and the like, (iv) the like and combinations thereof. In some embodiments, a cage rack has a rack mounted circuit board hub in functional association with each air connector plate. In certain embodiments, a cage rack has a blower control board in functional association with each modular blower system. In some embodiments, the blower control boards are functionally and/or physically associated with a circuit board hub.

In certain embodiments cage rack controller boards include independent circuit boards with one or more functions, and in some embodiments cage rack controller boards include a master controller board which controls the functions of other functionally associated circuit boards. In certain embodiments a circuit board includes a circuit board hub, for functional association with one or more other controller boards or a master rack controller. In certain embodiments a rack controller is functionally associated with one or more blower controllers, one or more circuit board hubs, or one or more blower controllers and one or more circuit board hubs. Communication between the various control boards is by wired communication media, in some embodiments, and in certain embodiments communication between one or more boards is by wireless communications (e.g., Wi-fi, Bluetooth, and the like).

Circuit Board Hub

A circuit board hub can generally include one or more receivers or connections for electrical power and one or more communication media and identifiers. Identifiers can encode any information related to a rack and cages. In a certain embodiments, an identifier encodes information related to the configuration of the cages in a rack, and/or the number of racks on a trolley (e.g., single cage rack embodiment, dual cage rack embodiment). Such information can be communicated to a fan unit such that it adjusts accordingly. In some embodiments, a circuit board hub is in effective connection to a rack unit. In certain embodiments the circuit board hub includes an identifier for the configuration of the cages in a rack and/or the number of racks on a trolley, a receiver for electrical power, a receiver for communication medium and a connector for a control.

With reference to FIGS. 24-27, 36-37, 47, 50-51, 56-57, 60, 70-71, 77, and 80-81 circuit board hub 900, 900′ attached to rodent containment cage 500 includes an identifier for the cage configuration of cages 20 in rack 500, in some embodiments. In certain embodiments the identifier includes circuit board 902. Circuit board hub 900 also includes a receiver for wiring from the rack, a connector for a control unit and a receiver for electrical power. In some embodiments, the receiver for wiring from the rack includes communication medium receptacle 912, and in certain embodiments, communication medium receptacle 912 is an eSATA receptacle. In embodiments illustrated in FIGS. 70-71 and 77, an eSATA communication medium receptacle is present but not visible in the views FIGS. 70-71 and 77. In some embodiments, a connector for a control unit includes controller port 910, and in certain embodiments, controller port 910 is a category 5 twisted pair high signal integrity (e.g., CAT5 or CAT-5) cable receiver or port. In some embodiments, a receiver for electrical power includes a Deutsch receptacle 906. In certain embodiments (e.g., embodiments illustrated as 900′) a Deutsch receptacle 906 is not included. Circuit board hub 900 also includes bores 904 for mounting to air connector plate 584, 586, and blind mate connector 908.

Circuit board hub 900, 900′ functions to (i) distribute power from power supply 740, via power supply wires 742 and (ii) distribute signal and information from various sensors or control boards (e.g., blower control boards 920, other circuit board hubs 900, 900′, master controller board 930, and combinations of the foregoing). Information is distributed between various controller boards using communications recommended standard 485 (e.g., RS-485) bridge. Circuit board hub 900, 900′ also includes a 12 volt (12V) power input and 3.3V buck mode switching power supply (not shown) to supply power to cage mount front module readers 564, as well as a 3.3V logic level serial bus (TTL) interface for communication with cage mount front module readers 564.

Blower Control Board

A blower control board can generally include one or more receivers or connections for electrical power and one or more communication media and identifiers. Identifiers can encode any information related to a rack and cages. In a certain embodiments, an identifier encodes information related to the configuration of the cages in a rack, the number of racks on a trolley (e.g., single cage rack embodiment, dual cage rack embodiment), and/or the number of blowers in effective connection with the rack. Such information can be communicated to a fan unit such that it adjusts accordingly. In some embodiments, a blower control board is in effective connection to a modular blower system which in turn is in effective connection with a rack unit.

With reference to FIGS. 45, 46, and 74-76 blower control board 920 includes connector 922, which functions to functionally and physically connect blower control board 920 and circuit board hub 900, 900′. Blower control board 920 also includes a connector (not shown) which functionally and operationally connects pressure sensor ports 616, 716 (see FIGS. 43 and 44) to blower control board 920 in modular blower system 600, 700 base 620, 621, 720, 721. Blower control board 920 functions to control the flow of air into and out of cage rack 500 by monitoring differential pressure developed by fan units 604, 704 of modular blower system supply blower 600 and exhaust blower 700. Fan 604, 704 (see FIG. 42) speed is regulated via proportional/integral servo software algorithms by matching fan speed to a differential pressure set point. In some embodiments fan speed curves are stored in blower control board 920, and in certain embodiments fan speed curves are stored in rack controller 930.

Blower control board 920 includes a 12V power input and an RS-485 communication bridge to allow communication via an American standard code for information interchange (e.g., ASCII) Modbus. ASCII modbus is a serial communications protocol often utilized to enable communications between electrical components in the same network. Blower control board 920 also determines functional status of fans 604, 704 by monitoring fan tachometers to sense a locked fan rotor. Identification of a locked fan rotor initiates a shutdown of the inoperative fan and/or entire modular blower system if the blower in question has only 1 fan, and also communicates an error message to rack control board 930.

Rack Controller Board

A rack controller board can generally include one or more receivers or connections for electrical power and one or more communication media and identifiers. Identifiers can encode any information related to a rack and cages. In a certain embodiments, an identifier encodes information related to the configuration of the cages in a rack, the number of racks on a trolley (e.g., single cage rack embodiment, dual cage rack embodiment), and/or the number of blowers in effective connection with the rack. Such information can be communicated to a fan unit such that it adjusts accordingly. In some embodiments, a rack controller board is in effective connection to a (i) on or more circuit board hubs, (ii) one or more modular blower systems which in turn are in effective connection with a rack unit (iii) one or more cage mount front module readers, and (iv) a power supply.

With reference to FIGS. 26-30, rack controller 930 functions are the master controller for all systems included in cage rack 500 (e.g., cage ID readers, modular blower systems, power distribution, communications, the like and combinations thereof). Rack controller 930 includes a 12V power input for supplying power to the graphical user interface utilized by a user to monitor rack status and/or input information. Rack controller 930 also includes wired and wireless communications capability (e.g., RS-485, Wi-fi, respectively) and a USB host port.

Rack controller 930 functions to calculate the appropriate differential pressure to each blower control board from user flow and differential flow set points. Rack controller 930 can store user input information in some embodiments, and in certain embodiments also logs various operational parameters of cage rack 500 including, but not limited to actual air flow, pressure values, error alarms or messages. Rack controller 930 can use information obtained from various identifiers for calculations used in rack operation. In some embodiments, an identifier may monitor cage conditions such as air pressure in a cage rack. In certain embodiments, an identifier may be determined using data from other identifiers, and in some embodiments, an identifier may be used to initiate changes to cage conditions based on data obtained or determined from other identifiers (e.g., change fan speed based on differential air pressure measurements).

Sensors

Sensors may be included of any variety of configurations or types that may be used to monitor conditions within each individual cage supported by the rack system. Some of the cages status parameters that may be monitored within each cage interior by remote sensors or other means may include the presence or level of viruses or bacteria, heat, noise, ammonia levels, carbon dioxide levels, carbon monoxide levels, humidity levels, air pressure levels, and the like. Sensors may monitor visual movement, olfactory changes, tactile changes, as well as auditory levels. Other parameters that may be monitored may include total animal weight within each cage, animal physical activity and/or body heat within each cage or other animal behavior or dynamics within each cage. Thus sensors may be in the form of a video camera, heat sensor, weighing apparatus and the like. For some embodiments, sensors that determine one or more of the above parameters may be disposed within each cage but also may be disposed within a conduit of the shelf assembly or plenum adjacent the shelf assembly. In certain embodiments, a rack includes an airflow or air pressure sensor. The sensor sometimes may be in connection with one or more tubes, conduits and/or metering nozzles. Any desired sensor or sensors may be disposed within the supply and exhaust passageways of the plenum, within the conduits an of the shelf assembly, within an interior volume of the cage assembly or at any other suitable position within the rack assembly.

Each sensor also may be operatively coupled to the controller in order to communicate the sensor's reading to the controller such that the sensor's data may then be processed and displayed on the graphic user interface. The information received from sensors and the information received from identifiers may be used together by the controller in order to locate cages or produce reports/status and the like to maintenance personnel.

An example of a sensor may be seen in FIGS. 8 and 21. FIG. 8 shows a perspective view of an embodiment of a cage 20 assembly suitable for use with the modular rack system 210. The sensor 140 is a remote sensor which monitors the cage interior. FIG. 21 shows a bottom view of the shelf 300 assembly of FIG. 6. Sensors 340 are disposed within the supply and exhaust passageways of the rack assembly and monitor airflow. These sensors may be directly coupled to the controller. FIG. 21 also shows the rim or lip portion 308 which extends around the perimeter of the shelf 300. The reader shelf mount 408 is fastened onto the rim 308. Also shown is the frame member 278 of the shelf 300 with a rail 276. In some embodiments, sensors can be disposed within the supply and exhaust passageways of rack embodiment 500 (e.g., within support member plenums 508, 510, side member plenums 522, 524 or support member plenums and side member plenums).

Some of the cage status parameters that may be monitored within each cage interior by remote sensors or other means may include the presence or level of viruses or bacteria, ammonia levels, carbon dioxide levels, carbon monoxide levels, humidity levels, air pressure levels, and the like. Cage content identifier data also aids in monitoring caged animals as well as the cage environment. Other parameters that may be monitored by sensors and/or identifiers may include total animal weight within each cage, animal physical activity within each cage or other animal behavior or dynamics within each cage.

Processors, Controllers and Servers

An animal containment system can include one or more processors, controllers and servers (e.g., main, local or remote server) in a convenient and suitable combination and configuration to carry out functions described herein. Systems described herein can allow for lab personnel to have the ability to reliably and conveniently monitor the interior conditions of each individual cage supported by a rack system with cage status information being conveniently and efficiently displayed.

In some embodiments, the rack system includes a controller and/or main/local server that may be coupled with, or be in wireless communication with, a blower assembly, one or more sensors, one or more readers and one or more indicators which are in association with identifiers in order to manage, maintain, track, and monitor a plurality of cages within the system. Identifiers provide data regarding the contents of the cage, data regarding the animals, inventory of non-cage items used for maintenance, cage components, users and/or maintenance personnel, location of the cages and the like. Sensors can include any of a variety of configurations or types that may be used to monitor conditions within each individual cage supported by the rack system (e.g., described in section herein entitled “Sensors”). The data obtained by the controller from the identifiers, sensors and/or other sources may be processed by a computing system disposed within the controller or any other suitable location in the system that may include a processor and data storage device and then displayed to a user. A display can be by an indicator (e.g., described herein) and/or on a graphic user interface in a convenient visual display format.

For some embodiments, a graphic user interface may contemporaneously display an icon or the like for each containment cage supported by a given rack system. For some embodiments, the icons displayed on the graphic user interface may be positioned on the screen in a configuration corresponding to the configuration of the actual cages of the rack system. In other words, a facsimile of a front view of a side of the actual rack system may be displayed on the screen of the graphic user interface such that lab personnel may immediately and intuitively assess the status of any of the cages on the rack system. The physical location of cages needing immediate attention may be identified to lab personnel by indicators/readers positioned on the shelf of each cage or in the vicinity of each cage. For some embodiments, the indicators and/or cage icons of the graphic user interface may use a color coded display to efficiently and rapidly convey cage status information to lab personnel. For example, if parameters are being monitored and processed are directed to determining the appropriate time to change a disposable cage to a new unused cage, different colors displayed by the indicators or graphic cage icons may be used to indicate the proximity of a necessary change. If the indicator and/or graphic cage icon color is green, no change is necessary, if the color is yellow, a change may be necessary soon and a red color may be used to indicate the need for an immediate cage change. If the color coding of the indicators near the cages and/or cage icons in a display on a graphic user interface is directed to cage change status information, lab personnel may select either or both of these parameter and view the indicators and/or icons at once to determine whether any cage changes are immediately necessary based on the presence of any red colored indicators and/or icons on the display. A similar scheme may be used for other parameters such as ammonia levels. If the lab technician selects ammonia level status, the color coding of the indicators/icons may then be switched to indicate whether ammonia levels are low, high or intermediate based on the different colors. Color coding may be used to indicate the need for attention by a veterinary professional for some embodiments.

A controller also may have such features as wireless access to an intranet or internet or other wireless device(s). The controller may either directly or indirectly be connected to a printer for printing reports, summary of experiments, documentation, inventory lists, bills, spreadsheets and the like. The controller may support video and audio functions as well as automated features such as sending an automated audio message or attached documents to a specified phone or emails, faxes and the like in response to an emergency situation, an alert, a warning or as a reminder or for monthly billing, inventory statements, summary of experiments, animal health status and the like. An electronic log of persons accessing the controller, time, duration and operations performed as well as information monitored by the identifiers and/or sensors may be stored in the controller's data storage. The display also may have a touch screen as well as a virtual keyboard displayed on the screen or a manual keyboard as part of the device and a speaker for voice recognition/input. The controller of each rack also may be in direct or wireless connection to a rack server. The rack server and/or management software system may coordinate schedules for all cages within the rack, manage maintenance, monitor all identifiers and sensors, and efficiently process all information through a user friendly display similar to those of the individual controllers. In some embodiments, the rack server and/or management software system may add information to one or more cages in a rack system, where the added information is added to the management software regarding cage component information, or directly to the cage by means of a read/write capable identifier.

Data from each identifier, which is manually recorded and/or detected by a reader or device, and each sensor can be received by or coupled to the controller to be processed and displayed on the graphic user interface.

As used herein, software or software modules refer to computer readable program instructions that, when executed by a processor, perform computer operations. Typically, software is provided on a program product containing program instructions recorded on a computer readable storage medium, including, but not limited to, magnetic media including floppy disks, hard disks, and magnetic tape; and optical media including CD-ROM discs, DVD discs, magneto-optical discs, and other such media on which the program instructions can be recorded. Software may be a computer program used to direct the operation of a computer. Software may be anything that is not hardware but is used with hardware. Software may be downloadable, portable, installed and/or accessed via an internet/wireless connection.

An algorithm stored in software and/or memory can be of any suitable type. In mathematics, computer science, and related subjects, an algorithm may be an effective method for solving a problem using a finite sequence of instructions. Algorithms are used for calculation, data processing, and many other fields. Each algorithm can be a list of well-defined instructions for completing a task. Starting from an initial state, the instructions may describe a computation that proceeds through a well-defined series of successive states, eventually terminating in a final ending state. The transition from one state to the next is not necessarily deterministic, for example, some algorithms incorporate randomness. By way of example, without limitation, the algorithm(s) can be search algorithms, sorting algorithms, merge algorithms, numerical algorithms, graph algorithms, string algorithms, modeling algorithms, computational genometric algorithms, combinatorial algorithms, machine learning, cryptography, data compression algorithms and parsing techniques and the like. An algorithm can include one or more algorithms working in combination. An algorithm can be of any suitable complexity class and/or parameterized complexity. An algorithm can be used for calculation or data processing, or used in a deterministic or probabilistic/predictive approach to a method in some embodiments. Any processing of data, such as by use with an algorithm, can be utilized in a computing environment, by use of a programming language such as C, C++, Java, Perl, Python, Fortran, and the like. The algorithm can be modified to include margin of errors, statistic analysis, statistical significance as well as comparison to other information or data sets (for example in using a neural net or clustering algorithm).

A database stored in software and/or memory can be of any suitable type. A database may be a comprehensive, systematic collection of related data organized for or manipulated to convenient, immediate access. A database also may be one or more large structured sets of persistent data, usually associated with software to update and query the data. A simple database might be a single file containing many records, each of which contains the same set of fields where each field is a certain fixed width. A database also may be a collection of nodes managed and stored in one place and all accessible via the same server. Links outside this may be “external”, and those inside may be “internal”. A database may be accessed and or stored in any manner, such as it may be downloadable, portable, installed and/or accessed via an internet/wireless connection. One or more databases may be used separately and in conjunction with one other. A database may be of any size, storing any amount of information or data. A database may store a few kilobytes of information or up to several thousand terabytes of data. A database may be one component of a database management system. Any type of database may be used, such as an analytic database, an operational database, hierarchical database, network database, relational database, and the like or combinations thereof.

Systems, machines or hardware discussed herein may further include general components of computer systems, such as, for example, network servers, laptop systems, desktop systems, handheld systems, personal digital assistants, computing kiosks, and the like. Hardware may be the mechanical equipment necessary for conducting an activity, usually distinguished from the theory and design that make the activity possible. In a computer system, hardware may include any mechanical, magnetic, electronic and or electrical device that comprises a computer system, such as the CPU, disk drives, keyboards, speakers, printers and screens/monitors. The computer system may include one or more input means such as a keyboard, touch screen, mouse, concept keyboards, light pens, tracker balls, joysticks, graphic tablets, scanners, digital cameras, video digitizers and voice recognition devices. or other means to allow the user to enter data into the system. The system may further include one or more output means such as a CRT or LCD display screen, speaker, FAX machine, impact printer, inkjet printer, black and white or color laser printer or other means of providing visual, auditory or hardcopy output of information. Electronic storage mediums that may be used to provide instructions/data to the controller and/or main or local server or provide storage/transportation from the controller/main/local server may be for example, a removable storage device, CD-ROMS, a hard disk installed in hard disk drive, signals, magnetic tape, DVDs, optical disks, flash drives, RAM or floppy disk, and the like.

The input and output means may be connected to a central processing unit which may comprise among other components, a microprocessor for executing program instructions and memory for storing program code and data. In some embodiments the methods may be implemented as a single user system located in a single geographical site. In other embodiments methods may be implemented as a multi-user system. In the case of a multi-user implementation, multiple central processing units may be connected by means of a network. The network may be local, encompassing a single department in one portion of a building, an entire building, span multiple buildings, span a region, span an entire country or be worldwide. The network may be private, being owned and controlled by the provider or it may be implemented as an internet based service where the user accesses a web page to enter and retrieve information.

The present methods may be implemented using hardware, software or a combination thereof and may be implemented in a computer system or other processing system. An example computer system may include one or more processors. A processor can be connected to a communication bus. The computer system may include a main memory, preferably random access memory (RAM), and can also include a secondary memory. The secondary memory can include, for example, a hard disk drive and/or a removable storage drive, representing a floppy disk drive, a magnetic tape drive, an optical disk drive, memory card etc. The removable storage drive reads from and/or writes to a removable storage unit in a well-known manner. A removable storage unit includes, but is not limited to, a floppy disk, magnetic tape, optical disk, etc. which is read by and written to by, for example, a removable storage drive. As will be appreciated, the removable storage unit includes a computer usable storage medium having stored therein computer software and/or data.

The computer system may also include a communications interface. A communications interface allows software and data to be transferred between the computer system and external devices. Examples of communications interface can include a modem, a network interface (such as an Ethernet card), a communications port, a PCMCIA slot and card, a wireless digital controller, etc. Software and data transferred via communications interface are in the form of signals, which can be electronic, electromagnetic, optical or other signals capable of being received by communications interface. These signals are provided to communications interface via a channel. This channel carries signals and can be implemented using wire or cable, fiber optics, a phone line, a cellular phone link, an RF link, an IR link, and other communications channels. Thus, in one example, a communications interface may be used to receive signal information to be detected by the signal detection module.

FIG. 10 illustrates the system architecture of the controller 230 embodiment which maintains information regarding containment cage status. The three levels of servers for the rack, local and main servers can each act alone or in combination with each other. FIG. 10 shows an example of two rack systems each having their own rack server (RS), controller 230, and one or more cage assemblies. The rack systems may be connected either by hardware or wireless connection (as depicted in FIG. 10) to one or more local servers (LS). The local server (LS) may serve several functions or be programmable to have additional functions. The local server may host any type of user interface, such as a flash interface, communicate with one or more rack systems, retrieve updates from a main server, send or generate alerts (e.g., alarm by room, alarm by build, alarm by site, administrative communication (e.g., pages, texts, email)), report generic status to the main server, function as a web server and local database, provide backup to the individual rack servers, provide extra memory for the controller, and host a management software system. The local server also may be directly connected or wirelessly connected to a user friendly portable device such as a smart phone or tablet personal computer, which may be handheld and easily accessed by users while performing maintenance on cages within a rack system. Such a feature provides easy of use in order to maintain a log of services and/or costs per cage or update information into the database. The local server can have a programmable processor that monitors the rack settings as well as log maintenance and export the information into a graphical display, such as a bar graph which can be viewed on a viewing device, a digital controller, a smart phone or table PC, for example. The main server (for example an Innovive Server—IS) may be wireless in communication to the local server in order to send updates or maintain programs or functions for each server. The main server may also collect site wide status for various locations and provide a hosting network as well as a management software system. The main server may also act as a web server, offer customer support when a need arises and maintains a backup database and/or extra memory space. A rack system need not use a local server or main server but be self sufficient. In another embodiment, one or more rack assemblies may only use one local server. In yet another embodiment, a rack system may use only a main server without a local server. Any combination of system architecture is possible.

Management Software

Any type of software that can manage, handle, direct and/or control maintenance of the cage system may be used. Such management software may have specific modules that perform certain functions, or the software may utilize or access other sources or software that can either perform tasks and/or give data which aids in managing the cage system. The management software may be stored/housed and/or accessed within a main, local and/or remote server. The management software also may be located in the controller. The software may also include other software, which performs such tasks as scheduling, cost control, budget management and billing, tracking, relational database management, communication, documentation or reporting, and/or administration systems or user access, which may be used to manage one or more cage racks/systems found in one or more locations. For example, the software system may track all animal colony information and related research data, from animal information (e.g. names, date of birth, genotypes, pedigree, or any other defined field), cages information (e.g. location, setup date, transferring history, cleaning schedule etc.), experiments, measurements, and the like. Scheduling may include sending convenient reminders with e-mail options may aid in managing the animals/cages and experiments more efficiently. Scheduling also may include management of support personal and/or resources (re-order reminders, stock levels of one or more cage components, and the like). Use of the software system may reduce cost, for example by removing extra cages or animals not in use.

Identifier data and information from other sources may be used alone or in combination with identifier data which may include caged animals or specimen housed within the cage, or environmental conditions or cage/rack information. For example, information from the controller regarding the current environmental conditions of the caged animals may be cross referenced via the internet for information regarding appropriate oxygen, ammonium, and carbon dioxide levels for particular animals in order to determine whether the caged environment is appropriate and to notify maintenance personnel. Such current environmental conditions may be received by the controller from a sensor. Information about the number of animals in a cage and the type of animals in a cage may be send to the controller from a cage content identifier. Other data sources, such as simulated data or database information, for example, may be received or downloaded from another computer or processor or by any known method such as for example, via the internet, via wireless access, via hardware such as a flash drive, manual input, voice recognition, laser scanning, bar code scanning, and the like. Such external information may be accessed, cross-referenced, integrated, manipulated, compared and downloaded with the internal information in the controller and/or local server manually by a person, automatically via a machine, programming and/or an algorithm, or in response to an alert or certain threshold indicators such as a sensor or on a by need basis, for example. Prediction algorithms may be used in order to determine significance or give meaning to the data collected under variable conditions that may be weighed independently of or dependently upon each other.

The data or information gathered from the various identifiers such as the cage content, cage user, cage component, and/or cage condition identifiers may be reported, documented and/or displayed in any form (i.e. digital data) and transformed or created into representations of that data, such as for example into a graph, a 2D graph, a 3D graph, and a 4D graph, a picture, a pictograph, a chart, a bar graph, a pie graph, a diagram, a flow chart, a scatter plot, a map, a histogram, a density chart, a function graph, a circuit diagram, a block diagram, a bubble map, a constellation diagram, a contour diagram, a cartogram, spider chart, Venn diagram, nomogram, and combination thereof.

It may be appreciated that many applications of the present invention could be formulated. The management software may access or include any other system, hardware or software for exchanging or processing data or transacting business, such as the Internet, an intranet, an extranet, WAN, LAN, satellite communications, and/or the like. The users may interact with the system via any input device such as a keyboard, mouse, kiosk, personal digital assistant (e.g., Palm Pilot), handheld computer, cellular phone, smart phone, tablet and/or the like. Similarly, the invention could be used in conjunction with any type of personal computer, network computer, workstation, minicomputer, mainframe, or the like running any operating system such as any version of Windows, Windows NT, Windows2000, Windows 98, Windows 95, MacOS, OS/2, BeOS, Linux, UNIX, Solaris or the like. The software system may be shared with group members while having full security control. Because the software system is portable and/or accessible anywhere with internet connection, the information/data stored/accessed will be accurate, with no synchronization needed.

Processing Data/Statistical Analysis

A management software system may be included in a system and can use any variety of statistical analysis software and/or modules to help properly manage the cage system. Statistical methods, algorithms and/or software modules can be applied to process data collected by the identifiers, sensors and other sources described herein. The controller, main, and/or local server may aid in applying such statistical methods, algorithms, and/or software modules to the gathered data in order to pre-process or standardized or normalize it in order to process it into a format that is understandable or can conform and hence be compared with other data. One or more of statistics, probability theory, data mining, pattern recognition, artificial intelligence, adaptive control, theoretical computer science or any algorithm can be employed for recognizing complex patterns and making intelligent decisions or connections within the data, for example.

The data or information gathered from various identifiers such as the cage content identifiers, cage user identifiers, cage component identifiers, and/or cage condition identifiers may be pre-processed, standardized or normalized to conform to a particular standard. For example, a pre-processing step sometimes aids in normalizing data when tracking environmental conditions over a particular period of time when comparing two different animal types which require different amounts of oxygen. Pre-processing may involve removing irrelevant data, outliers, or false-positives, for example. Normalization can be carried out in a variety of manners. For example, oxygen requirement data can be normalized across all samples by subtracting the mean or by dividing the oxygen values by the standard deviation to obtain centered data of standardized variance. Other examples of normalizing data is by using the log median intensity protocol, applying a median intensity normalization protocol in which raw intensities for all spots in each sample are normalized by the median of the raw intensities, or using the Z-score mean absolute deviation of log intensity protocol, for example. In some embodiments, intensity background correction is used to normalize measurements.

Statistical analysis or comparison may alert a user or personnel of human error. For example, when an animal has been placed in the wrong cage based on past/current weight change at a specific cage location within rack after cages have been taken out of the rack for maintenance, statistical analysis software, algorithms and/or software modules may identify the two or more cages which were switched from their previous location within the rack. In other embodiments, statistical analysis may detect when a soiled component is reused or not changed out within a cage after maintenance has been performed based on weight or odor of the soiled component verses a new component. Such analysis may aid in identifying anomalies or experimental errors, for example, when one experimental animal is not performing as expected, genetic lineage, cage history, vet history and the like may aid in excluding that animal from the experiment.

Electronic Modules

An electronic, computer or digital module may be a separate component that can be interchangeable with other electronic modules, or optionally embodied in software, that is stored on a program product. An electronic module may be a self-contained segment designed to perform a particular task and/or part of a program that performs a distinct function. A module also may be a plug-in hardware unit, and/or a downloadable, portable, installed software program and/or accessed via an internet/wireless connection. Modules may reside in or be part of the management software system, controller, local server and/or main server.

The management software system, controller, local server and/or main server may have any modules necessary to maintain, manage, locate/track, and/or monitor the cages in a cage rack system. Modules may include a receiving module, an association module and a data display module and the like.

A receiving module may receive any type of data, signal, and/or information by any manner. By “receiving” or “obtaining” information is meant receiving, providing and/or accessing the signal information by computer communication means from a local, or remote site, human data entry, or any other method of receiving signal information.

The information may be generated in the same location at which it is received, provided, accessed, or it may be generated in a different location and transmitted to the receiving, provided or accessed location. Received information may be stored locally, remotely, off-site, or transmitted elsewhere. The information may be digital or electronic information.

A receiving module may receive all information detected by readers in connection with the controller on the cage rack system as well as handheld readers or readers functioning remotely. Information detected by readers may be identifier data such as cage content data which relates to the occupancy of the animal cage such as the number and type of animals in a cage, the owner of a cage, the age of an animal, the sex of an animal, the pedigree of an animal, the experimental procedure planned for an animal, the observations/notes by a cage user, and the like. Readers may also detect cage user data which may contain information regarding users or personnel of the rack system or of one or more cages such as the personnel accessing a cage, the time of cage access, the date of cage access, the purpose of cage access and the like. Readers may also detect cage component data which may label or identify which object the identifier is located on, for example a cage lid component, a cage base component, an air supply component, an air exhaust component, a water supply component, a sensor component, a filter component, a baffle component or a feeder or components of a cage and the like. Readers may also detect cage condition data which may contain information regarding any conditional changes made to the inside or outside of the cage itself or any materials used in maintenance of the cages, such as a food change, a water change, a medicine administered to the occupants of the cage, a bedding material change, a filter change, a syringe administered to one or more animals, a glove used by personnel cleaning the cages, cleaning supplies used to clean the cages or the like. Cage condition data may also contain a time/date stamp of when the non-cage material was used or administration of a procedure in the cage or when the cage was maintained.

A receiving module may receive all information from all other sources of the cage rack system, such as the sensors, manual entry by a user, electronic messages to the system (i.e. emails, audio messages, faxes, document upload and the like), internet access and the like. Thus the receiving module may have access to or be in communication with or receive information from variety of different hardware and software components.

An association module may have access to data or information received by the receiving module in order to sort, track, manage, maintain, and establish relationships between the data. By “associating” or make an “association” and the like, is meant connecting, joining, linking, accompanying, sharing or making a relationship between objects, data and the like. An association module may be similar to or work in collaboration with a relational database. A relational database is an electronic database comprising data of related information, which allows links to be established between separate data that have matching fields, and responds to queries by a user regarding the data. Thus an association module receives data from the receiving module, associates the data into a relational database, and can identify objects and/or data or relationships in the data for the entire database.

For example, associations may be based on cage content data and/or cage content identifiers also known as cage card data/identifiers. The cage content data relates to the occupants of the animal cage and all cage content identifiers track actions, events, history and the like to be processed into or be added to the cage content data. Cage content data may begin with all the information on the physical cage card of each cage but additionally may contain more information regarding the occupants. All other identifiers (cage component, cage condition and cage user) and all other data (cage component, cage condition and cage user) may be associated with their corresponding cage content data and/or cage content identifier.

For example, a cage content identifier may be located on the front side of the cage bottom as well as on the flange of the cage bottom or on the flange of the corresponding cage lid, such that the identifiers for the lid, bottom and cage content may be in-line and easily detected by a reader mounted to the shelf of the cage. The receiving module receives the three identifiers' information from the reader, which may record time/date of when the cage was returned to the shelf, such that the association module then has access to the information. The association module then associates all the information based on or linked to the cage content identifier. If the cage bottom is changed and a new cage bottom identifier is detected by the reader with the cage lid identifier and the cage content identifier, the new cage bottom identifier will then be associated with that cage content identifier. The change in bottom identifiers will be processed or recorded/tracked as a change in a cage component, and specifically with a cage bottom. Such recording/tracking may aid in keeping accurate inventory of cage and non-cage items. Another example may involve a cage user such that when a user or lab personnel accesses a cage, the user must identify him or herself to the system to gain access by any means such as by password, pass code, voice recognition, identify verification and the like. Once the user has successfully accessed the rack system, the cage user identifier has been received by the receiving module, the association module having access to this information will associate the user with whichever cage content identifier is detected until the user logs out of the system. Such that if the user accesses two cages, then the user's cage user identifier will be associated with those two cage content identifiers within the time frame of when the user was logged into the rack system. Since those two cage content identifiers are associated with other identifiers such as cage component identifiers, then the user accessing the two cages will also be associated to the corresponding cage component identifiers because they are linked together by the cage content identifiers.

The association module may aid in determining user error, for example if two cage lids were accidentally switched, the association module would identify the error because the corresponding cage lid identifiers and their cage content identifiers would be detected at different locations and/or detected by different readers at possibly different times when the cages are place and read by readers into the shelves. A comparison of past associations with current associations also may be performed. A warning of possible human error may be trigger graphically via the controller and/or light indicators on the readers of the cages that were problematic.

Association may be user-defined or pre-programmed. As discussed above, if a cage content identifier and cage component identifier are detected by a reader at the same time/location within a rack system, then they may be associated or linked. This may be an example of a pre-programmed association based on same location and same time detected. Association may be based on identifiers being detected by the same reader, identifiers being detected at relatively the same time period, and the like. Also, a comparison of past associations with current associations also may be performed and pre-programmed. Associations also may be user-defined or re-programmed by approved personnel. If a user is changing cage components, then a re-programming instance may be allowed, for example. Thus the association module associates data or electronic/digital information and may be software based or uses only software.

A data display module may have access to all the associated data or information linked by the associated module in order to display data or organize the data or is a reporting function to the user. A data display module also may be referred to as a reporting module or a documentation module, and in some embodiments may display a report generated from a separate report module. A data display module may present or display data and/or associated data in any form to the user, such that the data presented is virtual, reproducible, orally, tactually, olfactorily, and/or printed representations of associated data by generating a list, an inventory report, security report, productivity report, graphics, a photograph, a virtual display of a rack module, a spreadsheet, a table, a graph, a 2D graph, a 3D graph, 4D graph, a picture, a pictograph, a chart, a bar graph, a pie graph, a diagram, a flow chart, a scatter plot, a map, a histogram, a density chart, a function graph, a circuit diagram, a block diagram, a bubble map, a constellation diagram, a contour diagram, a cartogram, a spider chart, a Venn diagram, a nomogram, combinations thereof and the like. The data display module may display the raw data, which is not associated. For example, the data display module may display a cage content identifier, cage component identifier, cage user identifier and cage condition identifier. The data display module may also display cage content data, cage component data, cage user data and cage condition data. The data display module may organize the associated date into easily recognizable, parsed, structured, and defined data such that the user may analyze the data in a managed fashion. For example, the data display module may display cage component identifier data recorded by date or by a time interval, such as one month. The data display module carries out a reporting or documenting function that may be user-defined and/or pre-programmed. The reports or documents that the data display module presents to the user may be static or manipulated and reformulated. The data display module may present specific reports based on user criteria and/or user query. The data display module, similar to the association module, may receive a request by a user to display information. The data display module may then access the relational or associated database, make associations with the data based on the user's query and present the data to the user. The date display module may use both software and hardware components, such as a database, printer, speaker, mister and the like.

The reports and other various forms of displayed and/or organized data may be presented to the user in a variety of ways. For some embodiments, a graphic user interface may contemporaneously display an icon or the like for each containment cage supported by a given rack system. For some embodiments, the icons displayed on the graphic user interface may be positioned on the screen in a configuration corresponding to the configuration of the actual cages of the rack system. In other words, a facsimile of a front view of a side of the actual rack system may be displayed on the screen of the graphic user interface such that lab personnel may immediately and intuitively assess the status of any of the cages on the rack system. The physical location of cages needing immediate attention may be identified to lab personnel by indicators/readers positioned on the shelf of each cage or in the vicinity of each cage. For some embodiments, the indicators and/or cage icons of the graphic user interface may use a color coded display to efficiently and rapidly convey cage status information to lab personnel. For example, if parameters are being monitored and processed are directed to determining the appropriate time to change a disposable cage to a new unused cage, different colors displayed by the indicators or graphic cage icons may be used to indicate the proximity of a necessary change. If the indicator and/or graphic cage icon color is green, no change is necessary, if the color is yellow, a change may be necessary soon and a red color may be used to indicate the need for an immediate cage change. If the color coding of the indicators near the cages and/or cage icons in a display on a graphic user interface is directed to cage change status information, lab personnel may select either or both of these parameter and view the indicators and/or icons at once to determine whether any cage changes are immediately necessary based on the presence of any red colored indicators and/or icons on the display. A similar scheme may be used for other parameters such as ammonia levels. If the lab technician selects ammonia level status, the color coding of the indicators/icons may then be switched to indicate whether ammonia levels are low, high or intermediate based on the different colors. Color coding may be used to indicate the need for attention by a veterinary professional for some embodiments.

A numeric display of the total number of cages requiring veterinary attention and the total number of cages requiring changing also may be shown both as a graphic display on the controller and digitally on the indicator/reader of each cage in the rack system. In another embodiment, numbers may be displayed within each cage icon in the controller to represent the number of animals housed within each cage. Such a display will quickly aid a user to determine which cages are empty, for example. Other features may include a password protection, messages, date/time display, menu, alerts and the like.

The graphic display on the controller may also show the air changes per hour “ACH” value which may be adjusted by toggling up and down arrows on the screen. The differential pressure between the supply conduits and the exhaust conduits indicated as “DIFF PRES” also may be displayed which is indicative of whether the cage assembly interiors have a net positive or negative pressure with respect to the ambient atmosphere. The “DIFF PRES” display also includes up and down arrows for adjustment of the relative pressures for achieving either positive or negative internal pressure within the cage assemblies. The date, time and other information also may be shown for reference by lab personnel. For some controller embodiments, various levels of access to the controller parameters and output may be controlled by requiring a passcode. For example, a pop up menu prompting a user passcode, that, when entered, will permit user access to the controller system for making adjustments and resetting parameters. Other pop up menus options may include “Configuring Your Rack”, “Configuring Cage Change Schedule” and other options. Access to such configuration settings may be restricted by the passcode access to only veterinary professionals or any other suitable level or group of personnel.

Selection 01 is the current option where the user is prompted with “Please identify which cages:” and to select from the drop down menu, with the options “Owned by Conger, Changed today, Changed last week, and In Fluoxetine Exp.” Once the user makes a selection, cages on the controller screen that match the criteria will be displayed with polka dots/texture. Selection 02 is a previous selection by the user which displays cages changed last week and has the cages color coded black. Selection 03 is also a previous selection by the user, which displays cages owned by Conger and has the cages color coded with striped lines. To the left of the selections is a facsimile of a front view of a side of the actual rack system where cages are color coded based on user selection and location of the cages. Indicators on the shelves of the rack system can also show location of cages based on user queries. Indicators as shown in FIGS. 5A-C, also may be color coded similar to the controller facsimile of FIG. 12, such that these indicators on the cage rack may show the user where cages are located based on their queries. If a user is interested in a particular cage shown on the controller facsimile, they may select that cage which will display the cage card information as shown in FIG. 11 where more information can be found, including a written description of the cage location in terms of M (modules; up to four modules can be on a rack), R (rows; up to 4 rows per module) and C (cages; up to eight cages per row). There is also a button with the option “Show Cage Location via Indicator on Rack,” where the selected cage's indicator will light up or be visually seen by the user on the cage rack once the button is selected/activated.

FIG. 13 shows a diagrammatic screen shot embodiment of the controller illustrating a cage change schedule. FIG. 13 illustrates a pop up menu 418 corresponding to the “Configure Cage Change Schedule” option. The change schedule menu includes a variety of change schedule options such as “normal”, “breeding” and “custom”.

Other features may include a password protection, messages, menu and the like.

FIG. 15 shows a diagrammatic screen shot embodiment of the controller illustrating an inventory of food as a bar graph. As seen in FIG. 14, a user option from the menu pop up is inventory. FIG. 15 shows an inventory of food for one month for cages in module 1, row 1, where the individual cages 1-8 are listed on the X-axis of the bar graph and ounces of food are listed on the Y-axis. Other time intervals may be selected such as one day, one week, and a user may type in another time interval selection, for example. Other modules also may be selected for the inventory graph, such as module 1, module 2, module 3 and/or module 4. Other displays of the inventory may be shown, as indicated by the graph format buttons, such as a line graph, calendar display or chart.

FIG. 16 shows a diagrammatic screen shot embodiment of the controller illustrating associated cage components. A summary of cage components (i.e. cage lid and cage bottom) which are associated with a particular cage card is displayed. Location of the cage at M1, R4 and C8 is also shown along with the identifier number: XMB 7845 and cage card symbol (smiley face). If other cage components were associated with this particular cage or cage card or cage content, then they would be listed on this screen.

FIG. 17 shows a diagrammatic screen shot embodiment of the controller illustrating an inventory summary over a one month time period. FIG. 17 shows a chart or list of racks, descriptions of the racks, number of cages per rack, number of cage lids, number of cage bottoms, status of rack, change frequency, and alarm setting for maintenance. A user may plan to order a certain number of cage lids and/or bottoms depending on this inventory summary. Cage bottoms may be more frequently changed out verses cage lids, depending on factors such as activity of the animals, number of animals per cage and the like.

FIG. 18 shows a diagrammatic screen shot embodiment of the controller illustrating airflow data in a list form. FIG. 18 illustrates a schedule or history of each rack, i.e. rack #1, which may include information for type (i.e. ACH or DP), value, time, and reference number for a history of the last 5 minutes, last hour, last 6 hours, last 12 hours, last day, last week, last month, all and the like.

FIG. 19 shows an embodiment of an association of data and/or identifier. A cage component identifier and corresponding cage content identifier have been received by the receiving module and associated together by an association module. Data from these identifiers have also been associated because their identifiers correspond to each other based on location within the rack system. An association module performs the task illustrated by FIG. 19 such that the cage component data 434 and cage content data 436 are associated 438. Association may be user-defined or pre-programmed.

FIG. 20 shows an operational procedure for locating specified cages based on user criteria. Cage lid 420, cage bottom 422 and cage card/content 424 are associated together 426 by an association module. A user selects a criteria 428 in order to locate one or more specific cages. The association module alone or in combination with the management software parses the associated information/data based on the user's criteria to identify the cage(s). A signal 430 is relayed to the cage rack system in order to identify the physical location of the cage(s) 432 by an indicator/reader in the vicinity of the cage(s). The signal 430 also may be relayed to the controller for a virtual graphic display to identify the location of the cage(s) 432.
